Abstract
The availability and accessibility of neurosurgical care across Africa remains limited despite recent advancements. Overall, Africa accounts for 15% of the global neurosurgical disease burden but has access to less than 1% of neurosurgeons globally. While the number of neurosurgeons has increased in recent decades, huge workforce shortages remain, with the region facing the second-largest neurosurgical deficit. Access to adequate facilities and equipment is also lacking. Barriers like poverty, conflicts, and distance from care centres negatively impact patients' ability to access services. However, training programs like the World Federation of Neurosurgical Societies Rabat Training Center have contributed to building local capacity. Use of technologies like neuro-endoscopy is expanding access to more cost-effective interventions for conditions such as hydrocephalus. Undergraduate medical education is also seeing a rise in African students interested in neurosurgery. Despite these advancements, workforce shortfalls, inadequate infrastructure, and challenges posed by geopolitical instability continue to hinder the provision of comprehensive neurosurgical care. Limited research and funding discourage experienced surgeons from practicing in their home countries. Increased international collaboration, support for education, and tackling of structural issues are needed to continue strengthening Africa's neurosurgical capacity and reducing the disease burden. This narrative review aims to provide an overview of the current state of neurosurgery on the continent, highlight achievements, and identify persisting challenges.

Abstract
The rapid progress that plasma wakefield accelerators are experiencing is now posing the question as to whether they could be included in the design of the next generation of high-energy electron-positron colliders. However, the typical structure of the accelerating wakefields presents challenging complications for positron acceleration. Despite seminal proof-of-principle experiments and theoretical proposals, experimental research in plasma-based acceleration of positrons is currently limited by the scarcity of positron beams suitable to seed a plasma accelerator. Here, we report on the first experimental demonstration of a laser-driven source of ultra-relativistic positrons with sufficient spectral and spatial quality to be injected in a plasma accelerator. Our results indicate, in agreement with numerical simulations, selection and transport of positron beamlets containingN e + ≥ 10 5 positrons in a 5% bandwidth around 600 MeV, with femtosecond-scale duration and micron-scale normalised emittance. Particle-in-cell simulations show that positron beams of this kind can be guided and accelerated in a laser-driven plasma accelerator, with favourable scalings to further increase overall charge and energy using PW-scale lasers. The results presented here demonstrate the possibility of performing experimental studies of positron acceleration in a laser-driven wakefield accelerator.

Abstract
This study aimed to explore the diuretic activity of linalyl acetate (LA). LA is an essential oil, it is an integral phyto-constituent of various plants. In this study, acute and chronic diuretic activities were explored by measuring the levels of different electrolytes and pH in the urine of experimental rats. Rats were divided into five groups. The control group was given 10 mg/kg normal saline, the treated group was given 10 mg/kg furosemide, and the remaining 3 groups received different doses of LA including 25, 50, and 75 mg/kg through intraperitoneal route, to determine its diuretic potential. Urine volume for acute diuretic activity was measured for 6 hours however for chronic diuretic activity was measured for 6 days. For a comparative study of LA with a control group and treated group with reference drug, diuretic index was used. Moreover, the underlying mechanism of the diuretic activity was also explored by comparing atropine, L-NAME, and indomethacin. The results of each group with 6 rats in each group were obtained by ± standard error of the mean of every group. Analysis of Variance (ANOVA) was used for statistical analysis. Results revealed that the LA 75 mg/kg dose showed comparable results as of furosemide. Moreover, this study revealed the involvement of muscarinic receptors to produce diuresis in comparison with atropine with very little involvement of prostanoids and no effect on NO pathway induced by indomethacin and L-NAME respectively. It is concluded that LA possess anti-diuretic potential. Muscarinic receptors might be involved in producing diuretic effects.

Abstract
Abstract Ligula intestinalis is a cestode parasite that affects freshwater fish in different countries of the world. The current study aims to reveal the phylogenetic, genetic and haplotype diversity of mt-CO1 gene sequences sent to the NCBI database from different countries by using in-silico analysis. The 105 mt-CO1 (371 bp) gene sequences of L. intestinalis obtained from NCBI were used for bioinformatics analyses. Sequences were subjected to phylogenetic and haplotype analysis. As a result of the haplotype analysis of L. intestinalis, 38 haplotypes were obtained from 13 different countries. Hap24 constituted 44.76% of the obtained haplotype network. Changes in nucleotides between haplotypes occurred at 1-84 different points. China and Turkey have highest fixation index (Fst) values of 0.59761, while the lowest (-0.10526) was found between Russia and Turkey. This study provides a baseline for future studies on extensive scale on the epidemiology, ecological aspects, distribution pattern, transmission dynamics and population dispersion of L. intestinalis worldwide.

Abstract
Tension impacts wound healing and scarring. Tissue stress reduces blood flow and promotes fibroblastic response in wound treatment. Botox injections reduce tension. A total of 18 male albino rats weighing 250-350 grams each got 1 IU of Botox and saline injected into a subcutaneous muscle in the center of each 1.5 CM two circles with 4.5 CM a gap between them. Group A seven days pre-operatively; group B, after wound incidence. The study compared Botox-treated wounds to those treated immediately after surgery. Group A animals were surgery-ready after 7 days, removed full-thickness skin. Group B got Botox and saline in separate cages following full-thickness skin excision. Each group had three equal subgroups. Each group had immunohistochemistry tests on days 3, 7, and 14. and histological test on day 14 only, Skin biopsies following euthanasia showed significant variations between A and B groups. On day three, the group A showed increase significantly MMP-9 expression than B group. On day 7, the group A displayed a significant increase CD31 expression, suggesting significant new blood vessel development than group B. On day 14, both groups showed strong MMP-9 and CD31 expression, demonstrated greater endothelial cell, and keratinocyte proliferation resulted in very well re-epithelialization. Botox injection before surgery improved wound healing and reduced fibrosis and scarring.

Abstract
There is a rising interest in studying the possible therapeutic value of fat-soluble micronutrients like vitamin K2 for preventing or controlling type 2 diabetes mellitus. The present study was designed to evaluate levels of vitamin K2 in patients with type 2 diabetes mellitus. The study enrolled 60 patients with type 2 diabetes mellitus and 30 individuals as a control group. Blood samples were collected from each participant for estimation of vitamin K2 by (ELISA), HbA1c by (Cobas), lipid profile by (colourimetric methods) and calculated BMI. The mean±Standard Deviation (SD) of vitamin K2 levels for the type 2 diabetes group were (185.13±30.08) pg/ml, with a highly significant decrease (p<0.001) when compared with the control group (303.91±58.60) pg/ml. The HbA1c, cholesterol, TG, and LDL-C level for the type 2 diabetes group highly significant increase (p<0.001) when compared with the control while HDL-C decreased when compared with the control group. The current study concluded that: Vitamin K2 levels showed a highly significant decrease in patients with uncontrolled type 2 diabetes mellitus when compared with those in the control group. Vitamin K2 levels play an important role in improving glycated haemoglobin and lipid profiles in patients with type 2 diabetes mellitus.

Abstract
We report the first search for a nonstandard-model resonance decaying into τ pairs in e^{+}e^{-}→μ^{+}μ^{-}τ^{+}τ^{-} events in the 3.6-10 GeV/c^{2} mass range. We use a 62.8 fb^{-1} sample of e^{+}e^{-} collisions collected at a center-of-mass energy of 10.58 GeV by the Belle II experiment at the SuperKEKB collider. The analysis probes three different models predicting a spin-1 particle coupling only to the heavier lepton families, a Higgs-like spin-0 particle that couples preferentially to charged leptons (leptophilic scalar), and an axionlike particle, respectively. We observe no evidence for a signal and set exclusion limits at 90% confidence level on the product of cross section and branching fraction into τ pairs, ranging from 0.7 to 24 fb, and on the couplings of these processes. We obtain world-leading constraints on the couplings for the leptophilic scalar model for masses above 6.5 GeV/c^{2} and for the axionlike particle model over the entire mass range.

Abstract
We report a measurement of the CP-violating parameters C and S in B^{0}→K_{S}^{0}π^{0} decays at Belle II using a sample of 387×10^{6} BB[over ¯] events recorded in e^{+}e^{-} collisions at a center-of-mass energy corresponding to the ϒ(4S) resonance. These parameters are determined by fitting the proper decay-time distribution of a sample of 415 signal events. We obtain C=-0.04_{-0.15}^{+0.14}±0.05 and S=0.75_{-0.23}^{+0.20}±0.04, where the first uncertainties are statistical and the second are systematic.

Abstract
We present the first measurement of the ratio of branching fractions of inclusive semileptonic B-meson decays, R(X_{e/μ})=B(B→Xeν)/B(B→Xμν), a precision test of electron-muon universality, using data corresponding to 189 fb^{-1} from electron-positron collisions collected with the Belle II detector. In events where the partner B meson is fully reconstructed, we use fits to the lepton momentum spectra above 1.3 GeV/c to obtain R(X_{e/μ})=1.007±0.009(stat)±0.019(syst), which is the most precise lepton-universality test of its kind and agrees with the standard-model expectation.

Abstract
Rapid pathogen identification is key to the proper management of patients with bloodstream infections (BSIs), especially in the intensive care setting. This multicentre study compared the time to pathogen identification results in 185 patients admitted to intensive care with a confirmed BSI, using conventional methods (n = 99 patients) and upon implementation of the BIOFIRE® Blood Culture Identification 2 (BCID2) Panel, a rapid molecular test allowing for the simultaneous identification of 43 BSI-related nucleic acids targets (n = 86 patients). The median time to result informing optimal antibiotic therapy was significantly shorter following the implementation of the BCID2 Panel (92 vs. 28 h pre vs. post BCID2 implementation; p < 0.0001). BCID2 usage in addition to conventional methods led to the identification of at least one pathogen in 98.8% patients vs. 87.9% using conventional methods alone (p = 0.003) and was associated with a lower 30-day mortality (17.3% vs. 31.6%, respectively; p = 0.019). This study at three intensive care units in the United Arab Emirates therefore demonstrates that, in addition to conventional microbiological methods and an effective antimicrobial stewardship program, the BCID2 Panel could improve the clinical outcome of patients admitted to the intensive care unit with a confirmed BSI.

Abstract
The need for bone tissue to heal effectively is paramount given its role in the mechanical support of tissues. Bone has a very good natural healing potential in comparison with most other tissue types, largely regenerating to its pre-injury state in the vast majority of cases. Certain factors such as high energy trauma, tumour resection, revision surgery, developmental deformities and infection can lead to the formation of bone defects, where the intrinsic healing potential of bone is diminished owing to bone loss. Various approaches to resolving bone defects exist in current practice, each with their respective benefits and drawbacks. These include bone grafting, free tissue transfer, Ilizarov bone transport and the Masquelet induced membrane technique. This review focuses on evaluating the Masquelet technique, discussing its method and underlying mechanisms, the effectiveness of certain modifications, and its potential future directions.

Abstract
The L_{μ}-L_{τ} extension of the standard model predicts the existence of a lepton-flavor-universality-violating Z^{'} boson that couples only to the heavier lepton families. We search for such a Z^{'} through its invisible decay in the process e^{+}e^{-}→μ^{+}μ^{-}Z^{'}. We use a sample of electron-positron collisions at a center-of-mass energy of 10.58 GeV collected by the Belle II experiment in 2019-2020, corresponding to an integrated luminosity of 79.7 fb^{-1}. We find no excess over the expected standard-model background. We set 90%-confidence-level upper limits on the cross section for this process as well as on the coupling of the model, which ranges from 3×10^{-3} at low Z^{'} masses to 1 at Z^{'} masses of 8 GeV/c^{2}.

Abstract
We search for lepton-flavor-violating τ^{-}→e^{-}α and τ^{-}→μ^{-}α decays, where α is an invisible spin-0 boson. The search uses electron-positron collisions at 10.58 GeV center-of-mass energy with an integrated luminosity of 62.8 fb^{-1}, produced by the SuperKEKB collider and collected with the Belle II detector. We search for an excess in the lepton-energy spectrum of the known τ^{-}→e^{-}ν[over ¯]_{e}ν_{τ} and τ^{-}→μ^{-}ν[over ¯]_{μ}ν_{τ} decays. We report 95% confidence-level upper limits on the branching-fraction ratio B(τ^{-}→e^{-}α)/B(τ^{-}→e^{-}ν[over ¯]_{e}ν_{τ}) in the range (1.1-9.7)×10^{-3} and on B(τ^{-}→μ^{-}α)/B(τ^{-}→μ^{-}ν[over ¯]_{μ}ν_{τ}) in the range (0.7-12.2)×10^{-3} for α masses between 0 and 1.6 GeV/c^{2}. These results provide the most stringent bounds on invisible boson production from τ decays.

Abstract
Musculoskeletal pain treatments are widespread in the clinical practice of physiotherapists. A multifaceted biopsychosocial approach should guide modern pain therapy. The study aimed to investigate the association of musculoskeletal problems with lifestyle behaviors. The study adopted a qualitative literature review methodology. About 200 papers have been reviewed for this study. The categories of the study had been classified according to the factors that are interconnected to the life intervention. The inclusion criteria of the selected literature depend upon the data received. This is a review-based study. The results of cross-sectional and correlational analysis dominated the literature on lifestyle implications on musculoskeletal health, which included pain and its correlated inflammation. Long-term prospective studies, however, are difficult to enroll in due to ethical concerns about denying patients' therapies shown to benefit them, notably lifestyle behavior modification. By conducting intervention studies, it determines lifestyle modifications that determine the beneficial aspects. These aspects are avoiding and reducing pain by increasing exercise capacity. The study concluded that the quantity of beneficial health practices boosted the health-related quality of life. To achieve long-term health, the complexity of the behaviour change needs to be supported by the individual's lifestyle pattern and the support of the data. Therefore, in this century characterized by chronic lifestyle-related illnesses, various health behavior modifications may be claimed to be a primary therapeutic skill of health professionals (individually and collectively).

Abstract
We study the processes e^{+}e^{-}→ωχ_{bJ}(1P) (J=0, 1, or 2) using samples at center-of-mass energies sqrt[s]=10.701, 10.745, and 10.805 GeV, corresponding to 1.6, 9.8, and 4.7 fb^{-1} of integrated luminosity, respectively. These data were collected with the Belle II detector during special operations of the SuperKEKB collider above the ϒ(4S) resonance. We report the first observation of ωχ_{bJ}(1P) signals at sqrt[s]=10.745 GeV. By combining Belle II data with Belle results at sqrt[s]=10.867 GeV, we find energy dependencies of the Born cross sections for e^{+}e^{-}→ωχ_{b1,b2}(1P) to be consistent with the shape of the ϒ(10753) state. These data indicate that the internal structures of the ϒ(10753) and ϒ(10860) states may differ. Including data at sqrt[s]=10.653 GeV, we also search for the bottomonium equivalent of the X(3872) state decaying into ωϒ(1S). No significant signal is observed for masses between 10.45 and 10.65 GeV/c^{2}.

Abstract
An absolute measurement of the Λ_{c}^{+} lifetime is reported using Λ_{c}^{+}→pK^{-}π^{+} decays in events reconstructed from data collected by the Belle II experiment at the SuperKEKB asymmetric-energy electron-positron collider. The total integrated luminosity of the data sample, which was collected at center-of-mass energies at or near the ϒ(4S) resonance, is 207.2 fb^{-1}. The result, τ(Λ_{c}^{+})=203.20±0.89±0.77 fs, where the first uncertainty is statistical and the second systematic, is the most precise measurement to date and is consistent with previous determinations.

Abstract
Dear Editor,
The ongoing Coronavirus disease 2019 (COVID-19) pandemic has affected a sizable portion of the global population, with over 410 million cases reported globally as of January 15, 20221. Pakistan has had its fair share of these cases, with over 1.4 million people testing positive for COVID as of the date mentioned above1. Antiviral drugs (remdesivir with or without baricitinib), steroids (dexamethasone), immunosuppressants (tocilizumab), monoclonal antibodies (casirivimab and imdevimab), and convalescent plasma have all been used to treat infected people2. Although antibiotics are not recommended for viral infections, they have been overprescribed in COVID patients2.
Pakistan is the world’s third- largest consumer of antibiotics among lower-middle income countries3. With antimicrobial resistance (AMR) already looming as a national concern4 and a history of the emergence of multiple antibiotic- resistant bugs5. One can safely assume that the use of antibiotics has likely escalated amidst the incessant COVID-19 pandemic in Pakistan. A study revealed non-evidence-based antimicrobials among patients with the COVID-19 admitted into Pakistani hospitals, prescription of antibiotics without established bacterial co-infections and an increased consumption of antibiotics such as azithromycin and ciprofloxacin in COVID patients6. This lends credence to our previously stated assumption.
The alarming upsurge in the prescription of antibiotics since the advent of the COVID-19 pandemic is bound to exacerbate the already rampant AMR in Pakistan and rest of the world alike. Several factors contribute to this predicament, including delays in diagnosis, inappropriate drug regimens, poor follow-up, lack of social support for high risk populations and now, due to COVID-19 pandemic, disruption in healthcare services, drug shortages, widespread use of biocides, misuse of antiobiotics and surge in misinformation4.
It is estimated that drug resistant infections kill more than 700,000 people worldwide each year, which likely to rise if the threat is not addressed4. Low- and middle-income countries (LMICs) like Pakistan are likely to suffer the worst consequences of AMR. In light of the potential aggravation of AMR stemming from antibiotic overuse in COVID patients, it is critical for regulating authorities to ensure that antimicrobial stewardship measures are followed when prescribing antibiotics and that non-evidence-based use is avoided. Since AMR is here to stay, the best thing that can be done in this pandemic is to prevent another bug from joining the notorious family of drug-resistant microorganisms.

Abstract
Support with VV-ECMO requires anticoagulation with unfractionated heparin to prevent thrombotic complications. This must be monitored due to bleeding risk. A point-of-care (POC) method of testing aPTT and APR was evaluated for agreement with laboratory methods. In a prospective observational study, patients supported on VV-ECMO as a result of severe respiratory failure secondary to Covid-19 infection were given heparin as part of standard therapy. The aPTT was measured (i) at the bedside using the Hemochron Signature Elite device and (ii) at the hospital laboratory. Duplicate results were compared. Agreement between the POC and laboratory tests was poor, as assessed using the Bland-Altman method. The maximum difference between POC and laboratory methods was 133% and the minimum was 0%. Overall bias was 7.3% and limits of agreement were between -43.8% and 58.5%. Correlation increased when results were normalised to platelet count and creatinine. This POC test is insufficiently accurate for use as the primary method of heparin monitoring in patients requiring VV-ECMO for Covid-19. Platelets and renal function may influence the result of this whole blood POC test.

Abstract
This record study aimed to investigate the prevalence of metabolic syndrome (MetS) profiles regarding sex, age, and obesity for the riskier factor of cardiovascular diseases in a general population in Saudi Arabia. Laboratory and anthropometric measurements were performed on non-specific participants with variant ages and BMI in either sex. Serobiochemical changes were measured for metabolic profiles, i.e., A1C/FSG, TC, TGC, HDLC/LDLC, Vit.D, TSH/T4, Hb, and Cr. The study was applied in a Polyclinic, Abha, Saudi Arabia in 2020 G. The general population showed variable incidences of MetS profiles, such as 69.4% diabetes, 85.5% hypothyroidism, and 92.2% obesity. Hypothyroidism showed a higher incidence in women rather than in men, but men were more dyslipidemic, with higher TGC and LDLC but low HDLC, compared to women. Men <40 Y. showed diabetes and hypothyroidism, but elders were dyslipidemic. Women <40 Y. showed anemia and hypovitaminosis-D but were suffering from hypothyroidism at all ages. Diabetes, hypothyroidism, hypovitaminosis-D, and dyslipidemia were the main MetS components in both overweight and obese participants, and an incidence of more than 50% in each profile was recorded. Diabetes with hypertension was characteristic of obese participants rather than those overweight. About 66.1% of the mixed-hypercholesterolemic cases were diabetic, but 18.9% of the mixed-diabetic participants were hypercholesterolemic. Castelli's risk factors, CRI-I and CRI-II, and atherogenic indices, AIP and AC, were measured for evaluating the cardiac risk in different populations based on the AUC-ROC and cut-off values. Insulin-resistance marker (TyG) was also measured, showing considerable cut-off values for diabetic susceptibility in the lipidemic participants with higher TGC and TC rather than HDLC or LDLC. In conclusion, MetS showed higher susceptibility to sex and age with increased incidence in women rather than men. However, the cardiac risk was more susceptible to men of higher TGC and low HDLC than women. Type 2 Diabetes mellitus (T2DM) was more prominent in both elders (≥40 Y.) than younger ages of either sex. Anemia and deficiency of Vit. D was characteristic of young women (<40 Y.). Hypothyroidism affects young men <40 Y. but was recorded in women of all ages. Both dyslipidemia and diabetes could trigger CVD, showing higher cardiac risk in mixed-hypercholesterolemic men rather than women. Our study strongly suggests that the consumption of unhealthy junk food, tobacco smoking, lack of exercise, and physical inactivity could be conclusive evidence of MetS in the Saudi population.

Abstract
Bovine brucellosis is an endemic zoonotic infection of ruminants in Pakistan with detrimental impacts on livestock economy. The major losses caused by brucellosis in animals include abortions, week calves, infertility, and reduced milk production. Regardless of the prevalence of the disease, limited data is available about brucellosis in Pakistan. The present study aimed to access the one health concept in prospective of Brucellosis among small-scale dairy farmers by examining knowledge, attitude and practices at the farms and household level that might pose a risk for humans contracting brucellosis. A community-based cross-sectional survey was conducted among small household dairy farms (n=333) in rural and urban areas of district Rawalpindi and Islamabad. The results revealed almost 74.17% of the participants knew about animal brucellosis and about 69.97% of the participants were able to identify the symptoms of animal brucellosis. 58.26% of participants showed knowledge about the transmission of disease from animals to humans. A majority (70.87%) of participants used the raw milk for making other dairy products. Most household farmers are unaware of routes of transmission and major risk factors of brucellosis. Almost all the participants, except veterinarians, including butchers, dairy farm owners and workers, slaughterhouse owners and workers and farmers were involved in at least one risky practice. The moderate knowledge and poor understanding of the disease emphasize the need to initiate awareness programs to educate the farmers who are at high risk along with the improvement of vaccination programs for animals and strict implementation of brucellosis eradication policy which should be devised by government.

Abstract
Information regarding deaths caused by poisoning or adverse effects of medication in Danish persons not using illicit narcotic drugs (PNUIDs) is sparse. To characterize aetiology, demographics, and death scene, we reviewed all legal autopsies performed at Aarhus University from 2017 to 2019 and isolated 96 deaths caused by medications in PNUIDs. Suicides caused by medication overdose accounted for 38%. Opioids and psychotropic medications were the main cause of death in 48% and 35% of the 96 cases, respectively. Morphine, tramadol, and quetiapine were the most commonly involved individual medications. A single medication caused death in 50% of cases, and multiple substances were involved in 50%. The median total number [interquartile range] of detected medications was 5 [4-6], with a higher number in females (5 [4-7]) than males (4 [2-5]), p = 0.009. Median age was 51 [42.5-61.5] years, and 57% were female. Scene of death most frequently involved a body on a bed or couch in the decedent's own home (72%). In conclusion, opioids and psychotropic medications dominated by morphine, tramadol and quetiapine most frequently caused medication-related deaths in PNUIDs. Monitoring this type of death may yield important knowledge to direct prophylactic initiatives regarding medication use and prescription.

Abstract
Abstract
Background
Differences in platelet aggregation response to generic clopidogrel by manufacturer has not been investigated.
Purpose
Compare rates of clopidogrel response among patients receiving medication produced by two different manufacturers after acute coronary syndrome and/or percutaneous coronary intervention.
Methods
This quality improvement project included 515 adult patients receiving clopidogrel for acute coronary syndrome or ischemic heart disease and referred for coronary angiography/percutaneous coronary intervention at a large, public hospital. The project was divided into two phases: 1. retrospective collection of baseline data; 2. two 12-week, prospective phases in which all clopidogrel in the hospital was restricted to a single manufacturer at a time. The primary outcome was clopidogrel response measured by platelet function testing defined as ADP response <40% on light transmission aggregometry between two manufacturer groups. Aspirin response defined as arachidonic acid response <20% was also measured.
Results
Of 515 total patients included in both phases (mean [SD] age, 64.5 [11.4] years; 351 [68.2%] men; 450 [87.4%] ACS), 52% were found to be clopidogrel responders based on results of platelet function testing (Table 1 – select variables). Among 135 patients in the prospective phase, there was a significantly lower proportion of patients who were clopidogrel responders in the Manufacturer 1 group compared to the Manufacturer 2 group (34.8% vs. 55.1%, p=0.03) (Table 2 – select variables). After adjustment for age, sex, BMI, aspirin response, therapeutic hypothermia, LHC indication, clopidogrel loading dose, time between loading dose and lab measurement, and manufacturer, aspirin response (OR [95% CI]: 0.96 [0.95–0.97], p<0.001) and manufacturer (OR [95% CI]: 2.45 [1.18–5.22], p=0.02) were associated with clopidogrel response.
Conclusions
In a large public hospital, we observed that pharmacodynamic response to clopidogrel varied by drug manufacturer. Further investigation and/or regulation is needed to minimize inter-manufacturer variability.

Abstract
BACKGROUND Primary hepatic leiomyosarcoma (PHL) is a rare tumor with a very low incidence of about 0.2%.
CASE SUMMARY A 48-year-old diabetic, hypertensive, and morbidly obese female patient presented with a history of abdominal pain and weight loss for 2 mo. She had no history of fever, jaundice, or other liver disease(s). Clinical examination revealed a palpable mass in the epigastrium. Imaging evaluation with a contrast-enhanced computed tomography (CT) scan of the abdomen and pelvis revealed an ill-defined enhancing hyper vascular hepatic mass of 9.9 cm × 7.8 cm occupying the left hepatic lobe with evidence of central necrosis, compression effect on the left hepatic vein, and partial wash-out on delayed images. On further workup, the maximum standardized uptake value on positron emission computed tomography scan was 6.4, which was suggestive of malignancy. The remaining part of the liver was normal without any evidence of cirrhosis. Ultrasound-guided biopsy of the mass showed smooth muscle neoplasm suggestive of leiomyosarcoma. After optimization for co-morbidities, an extended left hepatectomy was planned in a multidisciplinary team meeting. On intraoperative ultrasound, the left hepatic lobe was entirely replaced by a large tumor extending to the caudate lobe with a compression effect on the middle and left hepatic veins. Final histopathology showed nodular and whorled white tumor comprised of spindled/fascicular cells with moderate to severe pleomorphism and focal necrosis. The mitotic index was greater than 20 mitoses per 10 high-power fields. The resection margins were free of tumor. Immunohistochemistry (IHC) depicted a desmin-positive/ caldesmon-negative/discovered on gastrointestinal stromal tumor 1-negative/ cluster of differentiation 117-negative profile, confirming the definitive diagnosis as PHL.
CONCLUSION This case report highlights the rare malignant mesenchymal hepatic tumor. To confirm PHL diagnosis, one requires peculiar histopathological findings with ancillary IHC confirmation. Management options include adequate/complete surgical resection followed by chemotherapy and/or radiotherapy.

Abstract
Premature relativistic transparency of ultrathin, laser-irradiated targets is recognized as an obstacle to achieving a stable radiation pressure acceleration in the "light sail" (LS) mode. Experimental data, corroborated by 2D PIC simulations, show that a few-nm thick overcoat surface layer of high Z material significantly improves ion bunching at high energies during the acceleration. This is diagnosed by simultaneous ion and neutron spectroscopy following irradiation of deuterated plastic targets. In particular, copious and directional neutron production (significantly larger than for other in-target schemes) arises, under optimal parameters, as a signature of plasma layer integrity during the acceleration.

Abstract
There is insufficient clinical knowledge about xanthogranulomatous cholecystitis (XGC) due to biased reporting. This study aims to investigate the incidence of XGC and evaluate the clinical outcome regarding operative time, rate of conversion and intraoperative or postoperative complications. We included 1141 patients who underwent surgery for gallbladder disease between January 2019 and December 2021. Of 1141 patients who underwent cholecystectomy, XGC was seen in 10 (0.87%). The average age is 47 (24–81 years old) with a male to female ratio of 3:2. Biliary pancreatitis and obstructive jaundice are seen in two patients who did ERCP and stenting before surgery. One patient presented with a 4 cm necrotizing soft-tissue granuloma. The BMI was high, with class I obesity in five patients. Symptoms last from 1 to 12 weeks. One patient was only diagnosed preoperatively as XGC. Four out of 10 (40%) required more than 72 h of hospitalization. All patients underwent elective sitting surgery, with eight successfully managed by laparoscopy and one converted to open. The average operative time was 90 min (43–193 min), and a postoperative drain was inserted in four patients. The median follow-up is after 24 months (11–30 months), with no postoperative collection, bleeding, complication or readmission. XGC is a rare benign entity requiring no further action upon incidental discovery. Surgical resection is the cornerstone of management, with the laparoscopic approach considered feasible and safe. Four out of 10 patients might need more than 3 days of hospitalization. In the presence of mass, the frozen section can help guide the management.

Abstract
Abstract
Aim
COVID-19 has intensified the need for the NHS to almost utilise remote consulting technology overnight, with clinicians under increasing pressure to provide virtual services preferentially, in line with the NHS digital ideals. This study explores the clinician experience of virtual working during the pandemic in a large acute NHS Teaching Trust, and to identify the facilitators and barriers to remote consultations (RC).
Method
A multi-format online questionnaire was constructed and emailed to all 816 consultants across the trust. The survey was open for one month and during that time two reminders were sent. The data was tabulated and analysed using Microsoft excel.
Results
270 consultants responded to the questionnaire, giving a response rate of 33%, with 208 (77%) performing RCs. 92.8% of these (N=193) have increased the number of RC during the pandemic. 45.9% did not have their own office (N=124), with over half of those (N=63) sharing an office with 3 or more people. The majority of remote consultations were over telephone (82%) with only 54.4% feeling they had the right equipment for video consultations. The biggest barriers were patient related issues (technical, poor environment or not available at scheduled time).
Conclusion
The main challenges facing consultants, in the provision of virtual services were lack of appropriate hardware, an absence of a suitable environment, the prevalence of technical complications, and difficulties experienced by their patients. It is, therefore, important to recognise, both at an organisational level, and nationally, that virtual consultations may play a role in the worsening of health inequalities.

Abstract
The aims of this study were to investigate the clinical effectiveness and patient acceptability of a modified glass ionomer cement placed using the atraumatic restorative treatment (ART) technique to treat root caries, and to carry out microbiological analysis of the restored sites. Two clinically visible root surface carious lesions per participant were restored using ART. One was restored with commercial glass ionomer cement (GIC) (ChemFil® Superior, DENTSPLY, Konstonz, Germany) which acted as the control. The other carious root lesion was restored with the same GIC modified with 5% chlorhexidine digluconate (GIC-CHX; test). Patient acceptability and restoration survival rate were evaluated at baseline and after 6 months. Plaque and saliva samples around the test and control restorations were collected, and microbiological analysis for selected bacterial and fungal viability were completed at baseline, and after 1, 3, and 6 months. In total, 52 restorations were placed using GIC and GIC-CHX in 26 participants; 1 patient was lost to follow-up. After reviewing the restorations during their baseline appointments, participants indicated that they were satisfied with the appearance of the restorations (n = 25, 96%) and did not feel anxious during the procedure (n = 24, 92%). Forty-eight percent (n = 12) of the GIC-CHX restorations were continuous with the existing anatomic form as opposed to six for the GIC restorations (24%), a difference which was statistically significant (p = 0.036). There was no statistically significant reduction in the mean count of the tested microorganisms in plaque samples for either type of restorations after 1, 3, or 6 months. Restoration of carious root surfaces with GIC-CHX resulted in higher survival rates than the control GIC. ART using GIC-CHX may therefore be a viable approach for use in outreach dental services to restore root surface carious lesions where dental services are not readily available, and for older people and special needs groups.

Abstract
Historically, passive immunotherapy is an approved approach for protecting and treating humans against various diseases when other alternative therapeutic options are unavailable. Human polyclonal antibodies (hpAbs) can be made from convalescent human donor serum, although it is considered limited due to pandemics and the urgent requirement. Additionally, polyclonal antibodies (pAbs) could be generated from animals, but they may cause severe immunoreactivity and, once "humanized," may have lower neutralization efficiency. Transchromosomic bovines (TcBs) have been developed to address these concerns by creating robust neutralizing hpAbs, which are useful in preventing and/or curing human infections in response to hyperimmunization with vaccines holding adjuvants and/or immune stimulators over an extensive period. Unlike other animal‐derived pAbs, potent hpAbs could be promptly produced from TcB in large amounts to assist against an outbreak scenario. Some of these highly efficacious TcB‐derived antibodies have already neutralized and blocked diseases in clinical studies. Severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) has numerous variants classified into variants of concern (VOCs), variants of interest (VOIs), and variants under monitoring. Although these variants possess different mutations, such as N501Y, E484K, K417N, K417T, L452R, T478K, and P681R, SAB‐185 has shown broad neutralizing activity against VOCs, such as Alpha, Beta, Gamma, Delta, and Omicron variants, and VOIs, such as Epsilon, Iota, Kappa, and Lambda variants. This article highlights recent developments in the field of bovine‐derived biotherapeutics, which are seen as a practical platform for developing safe and effective antivirals with broad activity, particularly considering emerging viral infections such as SARS‐CoV‐2, Ebola, Middle East respiratory syndrome coronavirus, Zika, human immunodeficiency virus type 1, and influenza A virus. Antibodies in the bovine serum or colostrum, which have been proved to be more protective than their human counterparts, are also reviewed.

Abstract
Image plates (IPs) are a popular detector in the field of laser driven ion acceleration, owing to their high dynamic range and reusability. An absolute calibration of these detectors to laser-driven protons in the routinely produced tens of MeV energy range is, therefore, essential. In this paper, the response of Fujifilm BAS-TR IPs to 1-40 MeV protons is calibrated by employing the detectors in high resolution Thomson parabola spectrometers in conjunction with a CR-39 nuclear track detector to determine absolute proton numbers. While CR-39 was placed in front of the image plate for lower energy protons, it was placed behind the image plate for energies above 10 MeV using suitable metal filters sandwiched between the image plate and CR-39 to select specific energies. The measured response agrees well with previously reported calibrations as well as standard models of IP response, providing, for the first time, an absolute calibration over a large range of proton energies of relevance to current experiments.

Abstract
Lipopolysaccharide (LPS), also known as endotoxin, can trigger septic shock, a severe form of inflammation-mediated sepsis with a very high mortality rate. However, the precise mechanisms underlying this endotoxin remain to be defined and detoxification of LPS is yet to be established. Macrophages, a type of immune cells, initiate a key response responsible for the cascade of events leading to the surge in inflammatory cytokines and immunopathology of septic shock. This study was undertaken to determine whether the LPS-induced inflammation in macrophage cells could be ameliorated via CDDO-IM (2-cyano-3,12 dioxooleana-1,9 dien-28-oyl imidazoline), a novel triterpenoid compound. Data from this study show that gene expression levels of inflammatory cytokine genes such as interleukin-1 beta (IL-1β), interleukin-8 (IL-8), tumor necrosis factor alpha (TNF-α), and monocyte chemoattractant protein-1 (MCP-1) were considerably increased by treatment with LPS in macrophages differentiated from ML-1 monocytes. Interestingly, LPS-induced increase in expression of pro-inflammatory cytokine levels is reduced by CDDO-IM. In addition, endogenous upregulation of a series of antioxidant molecules by CDDO-IM provided protection against LPS-induced cytotoxicity in macrophages. LPS-mediated nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kB) transcriptional activity was also noted to decrease upon treatment with CDDO-IM in macrophages suggesting the involvement of the NF-κB signaling. This study would contribute to improve our understanding of the detoxification of endotoxin LPS by the triterpenoid CDDO-IM.

Abstract
Axionlike particles (ALPs) are predicted in many extensions of the standard model, and their masses can naturally be well below the electroweak scale. In the presence of couplings to electroweak bosons, these particles could be emitted in flavor-changing B meson decays. We report herein a search for an ALP, a, in the reaction B^{±}→K^{±}a, a→γγ using data collected by the BABAR experiment at SLAC. No significant signal is observed, and 90% confidence level upper limits on the ALP coupling to electroweak bosons are derived as a function of ALP mass, improving current constraints by several orders of magnitude in the range 0.175 GeV<m_{a}<4.78 GeV.

Abstract
We report on the first search for electron-muon lepton flavor violation (LFV) in the decay of a b quark and b antiquark bound state. We look for the LFV decay ϒ(3S)→e^{±}μ^{∓} in a sample of 118 million ϒ(3S) mesons from 27 fb^{-1} of data collected with the BABAR detector at the SLAC PEP-II e^{+}e^{-} collider operating with a 10.36 GeV center-of-mass energy. No evidence for a signal is found, and we set a limit on the branching fraction B[ϒ(3S)→e^{±}μ^{∓}]<3.6×10^{-7} at 90% C. L. This result can be interpreted as a limit Λ_{NP}/g_{NP}^{2}>80 TeV on the energy scale Λ_{NP} divided by the coupling-squared g_{NP}^{2} of relevant new physics (NP).

Abstract
The response of the BAS-TR image plate (IP) was absolutely calibrated using a CR-39 track detector for high linear energy transfer Au ions up to ∼1.6 GeV (8.2 MeV/nucleon), accelerated by high-power lasers. The calibration was carried out by employing a high-resolution Thomson parabola spectrometer, which allowed resolving Au ions with closely spaced ionization states up to 58+. A response function was obtained by fitting the photo-stimulated luminescence per Au ion for different ion energies, which is broadly in agreement with that expected from ion stopping in the active layer of the IP. This calibration would allow quantifying the ion energy spectra for high energy Au ions, which is important for further investigation of the laser-based acceleration of heavy ion beams.

Abstract
BACKGROUND The discrepancy between the endogenous antioxidants concentrations and free radicals results in oxidative stress and cellular injury. OBJECTIVE To appraise the usefulness of Rosemarinus officinalis (RO) aqueous extract in protecting buffalo spermatozoa during freezing / thawing process. MATERIALS AND METHODS Qualifying ejaculates from four well-restrained bulls were evaluated initially and then diluted in a freezing medium supplemented with RO-0.0, RO-0.5 %, RO-1.0%, RO-2.0 %, and RO-4.0 %, cooled to 4 degree C in 2 h, equilibrated for 4 h at 4 degree C, packed in straws, and cryopreserved, and thawed at 37 degree C for 30 s followed by evaluation. RESULTS We found that freezing medium supplemented with RO-2.0 % improves progressive motility (%) compared to the control. Similarly, a lower rate of apoptosis-like changes (%) was recorded with RO-4.0 % than the control, RO-0.5 % and RO-1.0 %. This response was accompanied by an increment in viable spermatozoa. Semen samples supplemented with RO-2.0 % and RO-4.0 % displayed higher TAC (total antioxidant capacity, uM per L) and ATP (nmol/million) content than the control. In addition, semen samples supplemented with RO-2.0 % displayed lower concentrations of ROS (reactive oxygen species, 104 RLU/20 min/25 million) than the control and RO-0.05 %. Also LPO (lipid peroxidation, uM per L) with RO-2.0 % and RO-4.0 % was lower than the control. CONCLUSION The inclusion of rosemary aqueous extract ameliorates motility features, structural and functional parameters, viability, TAC and ATP content of bull sperm. Conversely, the inclusion of rosemary aqueous extract alleviates apoptosis-like changes, ROS and LPO in comparison to the control. Further studies are required to determine the mechanism of action of rosemary aqueous extract in ameliorating semen quality and fertility of buffalo spermatozoa. doi.org/10.54680/fr22210110712.

Abstract
Anti-tuberculosis drugs are reported to cause hepatotoxicity, which varies from asymptomatic rise of the hepatic enzymes. Hepatoprotective plants plays important role to protect liver. This study investigated the hepatoprotective potential of the Solanum lycopersicum in rats intoxicated with Isoniazid and Rifampicin (INH+RIF) to induce hepatotoxicity. Thirty wistar albino rats were divided into five groups of six animals each. Group 1 rats were kept control while groups II, III, IV and V were administered with INH+RIF (75+150 mg/kg) orally, for seven consecutive days. For treatment, rats in group III received silymarin while animals in group IV and V were provided with 40 mg/kg and 80 mg/kg of Solanum lycopersicum extract, respectively. On day 0 and 8th blood samples were collected for the analysis of hepatic biomarkers. The data were subjected to one-way ANOVA and Bonferroni's post hoc test for statistical analysis. Hepatotoxicity induced by INH+RIF resulted in significant elevation of serum hepatic enzymes including Aspartate aminotransferase (AST), Alanine aminotransferase (ALT), Alkaline phosphatase (ALP), and total bilirubin while decreased the albumin level. The Solanum lycopersicum at dose of 80 mg/kg significantly reduced the hepatic enzymes AST, ALT, ALP and bilirubin while the albumin level was significantly increased. The treatment had non-significant effect on body and liver weight. Drug induced hepatotoxicity can be effectively treated with Solanum lycopersicum at 80 mg/kg dose.
