Abstract
Mostly, cardiovascular diseases are blamed for casualties in rheumatoid arthritis (RA) patients. Customarily, dyslipidemia is probably the most prevalent underlying cause of untimely demise in people suffering from RA as it hastens the expansion of atherosclerosis. The engagement of inflammatory cytokines like tumor necrosis factor-α (TNF-α), interleukin-1 (IL-1), interleukin-6 (IL-6), etc., is crucial in the progression and proliferation of both RA and abnormal lipid parameters. Thus, lipid abnormalities should be monitored frequently in patients with both primary and advanced RA stages. An advanced lipid profile examination, i.e., direct role of apolipoproteins associated with various lipid molecules is a more dependable approach for better understanding of the disease and selecting suitable therapeutic targets. Therefore, studying their apolipoproteins is more relevant than assessing RA patients' altered lipid profile levels. Among the various apolipoprotein classes, Apo A1 and Apo B are primarily being focused. In addition, it also addresses how calculating Apo B:Apo A1 ratio can aid in analyzing the disease's risk. The marketed therapies available to control lipid abnormalities are associated with many other risk factors. Hence, directly targeting Apo A1 and Apo B would provide a better and safer option.

Abstract
Development assistance is a major source of financing for health in least developed countries. However, persistent aid fragmentation has led to inefficiencies and health inequities and constrained progress towards Universal Health Coverage (UHC). Malawi is a case study for this global challenge, with 55% of total health expenditure funded by donors and fragmentation across 166 financing sources and 265 implementing partners. This often leads to poor coordination and misalignment between government priorities and donor projects. To address these challenges, the Malawi Ministry of Health (MoH) has developed and implemented an architecture of aid coordination tools and processes. Using a case study approach, we documented the iterative development, implementation and institutionalization of these tools, which was led by the MoH with technical assistance from the Clinton Health Access Initiative. We reviewed the grey literature, including relevant policy documents, planning tools and databases of government/partner funding commitments, and drew upon the authors' experiences in designing, implementing and scaling up these tools. Overall, the iterative use and revision of these tools by the Government of Malawi across the national and subnational levels, including integration with the government's public financial management system, was critical to successful uptake. The tools are used to inform government and partner resource allocation decisions, assess financing and gaps for national and district plans and inform donor grant applications. As Malawi has launched the Health Sector Strategic Plan 2023-2030, these tools are being adapted for the 'One Plan, One Budget and One Report' approach. However, while the tools are an incremental mechanism to strengthen aid alignment, success has been constrained by the larger context of power imbalances and misaligned incentives between the donor community and the Government of Malawi. Reform of the aid architecture is therefore critical to ensure that these tools achieve maximum impact in Malawi's journey towards UHC.

Abstract
Although gastrointestinal stromal tumours (GISTs) are encountered all along the gastrointestinal tract, duodenal GISTs are uncommon and account for <5% of the cases. A 45-year-old woman presented chiefly with anaemia and associated symptoms, whom on further evaluation was found to have a non-metastatic GIST in the distal duodenum sparing the pancreas and major vasculature. Patient was undertaken for segmental duodenectomy with the help of advanced bipolar energy device (tumour occupying D3-D4 with 1 cm proximal margin and 15 cm jejunum) preserving the pancreas and ampulla with end-to-end duodenojejunostomy with an uneventful postoperative course and clear margins on histopathology. Thus, the patient underwent a less morbid procedure with satisfactory oncological outcome and early resumption of activity. This highlights the need to conduct more trials to gather high level evidence in favour of conservative resection and its oncological adequacy and impact on overall survival and recurrence.

Abstract
OBJECTIVES Health benefits packages (HBPs), which define specific health services that can be offered for free or at a reduced cost to fit within public revenues, have been recommended for over 30 years to maximize population health in resource-limited settings. However, there remain gaps in defining and operationalizing HBPs. We propose a combination of design and prioritization methods along with practical strategies to improve the implementation of future iterations of the HBP in Malawi. METHODS For HBP development for Malawi's Third Health Sector Strategic Plan, we combined cost-effectiveness analysis with a quantitative, consultative multicriteria decision analysis. Throughout the process of development, we documented challenges and opportunities to improve HBP design and application. RESULTS The primary and secondary HBP included 115 interventions. However, the definition of an HBP is just one step toward focusing limited resources, with functional operationalization as the most critical component. Full implementation of previous HBPs has been limited by challenges in aid coordination with the misalignment of nonfungible vertical donor funding for the HBP without accounting for the complexity and interconnectedness of the health system. Opportunities for improved application include creation of a complementary minimum health service package to guide overall resource inputs through an integrative approach. CONCLUSIONS We believe that expanded participatory HBP methods that consider value, equity, and social considerations, along with a shift to providing integrated health service packages at all levels of care, will improve the efficiency of using scarce resources along the journey to universal health coverage.

Abstract
Misfolded and aggregated proteins build up in neurodegenerative illnesses, which causes neuronal dysfunction and ultimately neuronal death. In the last few years, there has been a significant upsurge in the level of interest towards the function of molecular chaperones in the control of misfolding and aggregation. The crucial molecular chaperones implicated in neurodegenerative illnesses are covered in this review article, along with a variety of their different methods of action. By aiding in protein folding, avoiding misfolding, and enabling protein breakdown, molecular chaperones serve critical roles in preserving protein homeostasis. By aiding in protein folding, avoiding misfolding, and enabling protein breakdown, molecular chaperones have integral roles in preserving regulation of protein balance. It has been demonstrated that aging, a significant risk factor for neurological disorders, affects how molecular chaperones function. The aggregation of misfolded proteins and the development of neurodegeneration may be facilitated by the aging-related reduction in chaperone activity. Molecular chaperones have also been linked to the pathophysiology of several instances of neuron withering illnesses, enumerating as Parkinson's disease, Huntington's disease, and Alzheimer's disease. Molecular chaperones have become potential therapy targets concerning with the prevention and therapeutic approach for brain disorders due to their crucial function in protein homeostasis and their connection to neurodegenerative illnesses. Protein homeostasis can be restored, and illness progression can be slowed down by methods that increase chaperone function or modify their expression. This review emphasizes the importance of molecular chaperones in the context of neuron withering disorders and their potential as therapeutic targets for brain disorders.

Abstract
Objective Therapy for osteoarthritis ideally aims at preserving structure before radiographic change occurs. This study tests: a) whether longitudinal deterioration in cartilage thickness and composition (transverse relaxation-time T2) are greater in radiographically normal knees "at risk" of incident osteoarthritis than in those without risk factors; and b) which risk factors may be associated with these deteriorations. Design 755 knees from the Osteoarthritis Initiative were studied; all were bilaterally Kellgren Lawrence grade [KLG] 0 initially, and had magnetic resonance images available at 12- and 48-month follow-up. 678 knees were "at risk", whereas 77 were not (i.e., non-exposed reference). Cartilage thickness and composition change was determined in 16 femorotibial subregions, with deep and superficial T2 being analyzed in a subset (n = 59/52). Subregion values were used to compute location-independent change scores. Results In KLG0 knees "at risk", the femorotibial cartilage thinning score (-634 ± 516 μm) over 3 years exceeded the thickening score by approximately 20%, and was 27% greater (p < 0.01; Cohen D -0.27) than the thinning score in "non-exposed" knees (-501 ± 319 μm). Superficial and deep cartilage T2 change, however, did not differ significantly between both groups (p ≥ 0.38). Age, sex, body mass index, knee trauma/surgery history, family history of joint replacement, presence of Heberden's nodes, repetitive knee bending were not significantly associated with cartilage thinning (r2<1%), with only knee pain reaching statistical significance. Conclusions Knees "at risk" of incident knee OA displayed greater cartilage thinning scores than those "non-exposed". Except for knee pain, the greater cartilage loss was not significantly associated with demographic or clinical risk factors.

Abstract
Recently, much attention has been paid to chronic neuro-inflammatory condition underlying neuropathic pain. It is generally linked with thermal hyperalgesia and tactile allodynia. It results due to injury or infection in the nervous system. The neuropathic pain spectrum covers a variety of pathophysiological states, mostly involved are ischemic injury viral infections associated neuropathies, chemotherapy-induced peripheral neuropathies, autoimmune disorders, traumatic origin, hereditary neuropathies, inflammatory disorders, and channelopathies. In CNS, angiogenesis is evident in inflammation of neurons and pain in bone cancer. The role of chemokines and cytokines is dualistic; their aggressive secretion produces detrimental effects, leading to neuropathic pain. However, whether the angiogenesis contributes and exists in neuropathic pain remains doubtful. In the present review, we elucidated summary of diverse mechanisms of neuropathic pain associated with angiogenesis. Moreover, an overview of multiple targets that have provided insights on the VEGF signaling, signaling through Tie-1 and Tie-2 receptor, erythropoietin pathway promoting axonal growth are also discussed. Because angiogenesis as a result of these signaling, results in inflammation, we focused on the mechanisms of neuropathic pain. These factors are mainly responsible for the activation of post-traumatic regeneration of the PNS and CNS. Furthermore, we also reviewed synthetic and herbal treatments targeting angiogenesis in neuropathic pain.

Abstract
BACKGROUND Carbapenem resistance is endemic in the Indian sub-continent. In this study, carbapenem resistance rates and the prevalence of different carbapenemases were determined in Escherichia coli, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa during two periods; Pre-COVID (August to October 2019) and COVID (January to February 2021) in a north-Indian tertiary care hospital. METHODS Details of patient demographics and clinical condition was collated from the Hospital Information System and detection of carbapenemases NDM, OXA-48, VIM, IMP and KPC was done by Polymerase chain reaction (PCR) in 152 and 138 non-consecutive carbapenem resistant isolates during the two study periods respectively. Conjugation assay and sequencing of NDM and OXA-48 gene was done on a few selected isolates. RESULTS As compared to Pre-COVID period, co-morbidities and the mortality rates were higher in patients harbouring carbapenem resistant organisms during the COVID period. The overall carbapenem resistance rate for all the four organisms increased from 23 to 41% between the two periods of study; with Pseudomonas aeruginosa and Klebsiella pneumoniae showing significant increase (p < 0.05). OXA-48, NDM and co-expression of NDM and OXA-48 were the most common genotypes detected. NDM-5 and OXA-232 were most common variants of NDM and OXA-48 family respectively during both the study periods. CONCLUSION Higher rate of carbapenem resistance in COVID times could be attributed to increase in number of patients with co-morbidities. However, genetic elements of carbapenem resistance largely remained the same in the two time periods.

Abstract
The term "neurodegenerative disorders" refers to a group of illnesses in which deterioration of nerve structure and function is a prominent feature. Cognitive capacities such as memory and decision-making deteriorate as a result of neuronal damage. The primary difficulty that remains is safeguarding neurons since they do not proliferate or regenerate spontaneously and are therefore not substituted by the body after they have been damaged. Millions of individuals throughout the world suffer from neurodegenerative diseases. Various pathways lead to neurodegeneration, including endoplasmic reticulum stress, calcium ion overload, mitochondrial dysfunction, reactive oxygen species generation, and apoptosis. Although different treatments and therapies are available for neuroprotection after a brain injury or damage, the obstacles are inextricably connected. Several studies have revealed the pathogenic effects of hypothermia, different breathed gases, stem cell treatments, mitochondrial transplantation, multi-pharmacological therapy, and other therapies that have improved neurological recovery and survival outcomes after brain damage. The present review highlights the use of therapeutic approaches that can be targeted to develop and understand significant therapies for treating neurodegenerative diseases.

Abstract
Alzheimer's disease (AD) is an insidious, multifactorial disease that involves the devastation of neurons leading to cognitive impairments. Alzheimer's have compounded pathologies of diverse nature, including proteins as one important factor along with mutated genes and enzymes. Although various review articles have proposed biomarkers, still, the statistical importance of proteins is missing. Proteins associated with AD include amyloid precursor protein, glial fibrillary acidic protein, calmodulin-like skin protein, hepatocyte growth factor, matrix Metalloproteinase-2. These proteins play a crucial role in the AD hypothesis which includes the tau hypothesis, amyloid-beta (Aβ) hypothesis, cholinergic neuron damage, etc. The present review highlights the role of major proteins and their physiological functions in the early diagnosis of AD. Altered protein expression results in cognitive impairment, synaptic dysfunction, neuronal degradation, and memory loss. On the medicinal ground, efforts of making anti-amyloid, anti-tau, anti-inflammatory treatments are on the peak, having these proteins as putative targets. Few proteins, e.g., Amyloid precursor protein results in the formation of non-soluble sticky Aβ40 and Aβ42 monomers that, over time, aggregate into plaques in the cortical and limbic brain areas and neurogranin is believed to regulate calcium-mediated signaling pathways and thus modulating synaptic plasticity are few putative and potential forthcoming targets for developing effective anti-AD therapies. These proteins may help to diagnose the disease early, bode well for the successful discovery and development of therapeutic and preventative regimens for this devasting public health problem.

Abstract
Rechargeable batteries based on Li-ion and post Li-ion chemistry have come a long way since their inception in the early 1980s. The last four decades have witnessed steady development and discovery of myriads of cathode materials taking into account their processing, economy, and performance along with ecological sustainability. Though oxides rule the battery sector with their high energy and power density, polyanionic insertion compounds work as gold mines for designing insertion compounds with rich structural diversity leading to tuneable redox potential coupled with high structural/chemical/thermal stability. The scope of polyanionic compounds can be taken a step further by combining two or more different types of polyanions to get suites of mixed polyanionic materials. While most cathodes are built with metal polyhedra constituted by oxygen (MOm|XOm, M = 3d metals, X = P, S, Si, B, W, etc., m = 3-6), in some cases, selected oxygen sites can form bonding with hydrogen to form OH/H2O ligands. It can lead to the family of hydroxy-based mixed-polyanionic cathode materials. The presence of hydroxy components can affect the crystal structure, local chemical bonding, and electronic, magnetic, diffusivity and electrochemical properties. Employing a mineralogical survey, the current review renders a sneak peek on various hydroxy-based polyanionic cathode materials for Li-ion and post Li-ion batteries. Their crystal structure, and electrochemical properties have been overviewed to outline future research focus and scope for real-life application.

Abstract
Assurance of substance abuse in plasma and different parts of the body is vital in clinical and legal toxicology. Detection techniques are evaluated for their appropriateness in scientific and clinical sciences, where extraordinary prerequisites must be met. Recognition and affirmation are for the most part done by gas chromatography-Mass spectrometry (GC-MS) or liquid chromatography (LC-MS), Surface-enhanced Raman spectroscopy (SERS), Magnetic resonance imaging, Positron Emission Tomography, Infrared Spectroscopy, and UV Spectroscopy. Progressed spectroscopic techniques provided helpful quantitative or qualitative data about the natural chemistry and science of exploited substances. These spectroscopic techniques are assumed as quick, precise, and some of them are non-damaging investigation apparatus that may be assumed as a substitution for previously used compound investigation. Spectroscopy with its advances in technology is centralized to novel applications in the detection of abused drug substances and clinical toxicology. These techniques have attracted growing interest as forensic tools for the early detection and monitoring of exploited drugs. This review describes the principle, role, and clinical application of various spectroscopic techniques which are utilized for the identification of drug abuse like morphine, cocaine, codeine, alcohol, amphetamines, and their metabolites in whole blood, plasma, hair, and nails.

Abstract
Alzheimer's is an insidious, progressive, chronic neurodegenerative disease which causes the devastation of neurons. Alzheimer's possesses complex pathologies of heterogeneous nature counting proteins as one major factor along with enzymes and mutated genes. Proteins such as amyloid precursor protein (APP), apolipoprotein E (ApoE), presenilin, mortalin, calbindin-D28K, creactive protein, heat shock proteins (HSPs), and prion protein are some of the chief elements in the foremost hypotheses of AD like amyloid-beta (Aβ) cascade hypothesis, tau hypothesis, cholinergic neuron damage, etc. Disturbed expression of these proteins results in synaptic dysfunction, cognitive impairment, memory loss, and neuronal degradation. On the therapeutic ground, attempts of developing anti-amyloid, anti-inflammatory, anti-tau therapies are on peak, having APP and tau as putative targets. Some proteins, e.g., HSPs, which ameliorate oxidative stress, calpains, which help in regulating synaptic plasticity, and calmodulin-like skin protein (CLSP) with its neuroprotective role are few promising future targets for developing anti-AD therapies. On diagnostic grounds of AD C-reactive protein, pentraxins, collapsin response mediator protein-2, and growth-associated protein-43 represent the future of new possible biomarkers for diagnosing AD. The last few decades were concentrated over identifying and studying protein targets of AD. Here, we reviewed the physiological/pathological roles and therapeutic significance of nearly all the proteins associated with AD that addresses putative as well as probable targets for developing effective anti-AD therapies.

Abstract
OBJECTIVES The study was aimed to evaluate the potential of hydroalcoholic extract of Pinus roxburghii (PRE) stem bark in post-menopausal osteoporosis and its underlying mechanisms. METHODS In silico docking of the markers was done using AutoDock version 4.2. for molecular targets: receptor activator of nuclear factor-κB (RANK), osteoprotegerin (OPG) and Cathepsin. Female Wistar rats of bodyweight 200-250 g were employed and surgical ovariectomy (OVX) was performed. PRE was administered at a dose of 100 and 200 mg/kg whereas standard drug, raloxifene given at 1 mg/kg orally for eight weeks. KEY FINDINGS PRE (20 and 40 µg/mL) significantly increased the cellular proliferation in osteoblastic UMR cell lines 11.58 and 15.09% respectively. Eight weeks after surgical removal of ovaries, a significant bone porosity was confirmed by modulation in bone breaking strength of tibia, lumber, and femur; bone mineral density (BMD), calcium, phosphorus, hydroxyproline levels in OVX group. Treatment with PRE 100 and 200 mg/kg significantly restored the bone loss. Real-time polymerase chain reaction (RT-PCR) analysis of molecular markers RANK, OPG and cathepsin and histology also confirmed the attenuation of bone loss. The quantification of quercetin, gallic acid, caffeic acid, catechin, tannic acid and ascorbic acid was done by high-performance liquid chromatography (HPLC) and high performance thin layer chromatography. CONCLUSIONS P. roxburghii produced anti-osteoporotic effect possibly due to estrogenic modulation, and improved bone remodeling.

Abstract
Huntington's disease (HD) is prototypical neurodegenerative disease, preferentially disrupts the neurons of striatum and cor-tex. Progressive motor dysfunctions, psychiatric disturbances, behavioural impairments and cognitive decline are the clinical symptoms of HD progression. The disease occurs due to, expanded CAG repeats in exon 1 of huntingtin protein (mHtt) causing its aggregation. Multiple cellular and molecular pathways are involved in the HD pathology. Mitochondria as vital organelles has an important role in most of the neurodegenerative diseases like HD. Over the years, the role of mitochondria in neurons are highly diverged, it not only contribute as cell power source, but as a dynamic organelles it fragments and then fuse to attain a maximal bioenergetics performance, regulate intracellular calcium homeostasis, reactive oxygen species (ROS) generation, antioxidant activity and involved in apoptotic pathways. Indeed, these events are seen to be affected in HD, resulting in neuronal dysfunction in pre-symptomatic stages. mHtt causes critical transcriptional abnormality by altering the expression of a master co-regulator, peroxisome proliferator-activated receptor gamma coactivator-1α (PGC-1α), leading to increased susceptibility to oxidative stress and neuronal degeneration. Moreover, mHtt influences multiple cellular signal-ling events which ends with mitochondrial biogenesis. Here, we resume recent findings that pose mitochondria as an im-portant regulatory organelle in HD and how mHtt affects mitochondrial function, trafficking and homeostasis and makes neurons prone to degeneration. In addition, we also uncover the mitochondrial based potential targets and therapeutic ap-proaches with imminent or currently ongoing clinical trials.

Abstract
BACKGROUND Alcohol abuse is a major problem worldwide and it affects people's health and economy. There is a relapse in alcohol intake due to alcohol withdrawal. Alcohol withdrawal anxiety-like behavior is a symptom that appears 6-24 h after the last alcohol ingestion. METHODS The present study was designed to explore the protective effect of a standardized polyherbal preparation POL-6 in ethanol withdrawal anxiety in Wistar rats. POL-6 was prepared by mixing the dried extracts of six plants Bacopa monnieri, Hypericum perforatum, Centella asiatica, Withania somnifera, Camellia sinesis, and Ocimum sanctum in the proportion 2:1:2:2:1:2 respectively. POL-6 was subjected to phytochemical profiling through LC-MS, HPLC, and HPTLC. The effect of POL-6 on alcohol withdrawal anxiety was tested using a two-bottle choice drinking paradigm model giving animals' free choice between alcohol and water for 15 days. Alcohol was withdrawn on the 16th day and POL-6 (20, 50, and 100 mg/kg, oral), diazepam (2 mg/kg) treatment was given on the withdrawal days. Behavioral parameters were tested using EPM and LDT. On the 18th day blood was collected from the retro-orbital sinus of the rats and alcohol markers ALT, AST, ALP, and GGT were studied. At end of the study, animals were sacrificed and the brain was isolated for exploring the influences of POL-6 on the mRNA expression of GABAA receptor subunits in the amygdala and hippocampus. RESULTS Phytochemical profiling showed that POL-6 contains major phytoconstituents like withaferin A, quercetin, catechin, rutin, caeffic acid, and β-sitosterol. In-vivo studies showed that POL-6 possesses an antianxiety effect in alcohol withdrawal. Gene expression studies on the isolated brain tissues showed that POL-6 normalizes the GABAergic transmission in the amygdala and hippocampus of the rats. CONCLUSION The study concludes that POL-6 may have therapeutic potential for treating ethanol-type dependence.

Abstract
Bone is one of the dynamic tissues in the human body that undergoes continuous remodelling through subsequent actions of bone cells, osteoclasts, and osteoblasts. Several signal transduction pathways are involved in the transition of mesenchymal stem cells into osteoblasts. These primarily include Runx2, ATF4, Wnt signaling and sympathetic signalling. The differentiation of osteoclasts is controlled by M-CSF, RANKL, and costimulatory signalling. It is well known that bone remodelling is regulated through receptor activator of nuclear factor-kappa B ligand followed by binding to RANK, which eventually induces the differentiation of osteoclasts. The resorbing osteoclasts secrete TRAP, cathepsin K, MMP-9 and gelatinase to digest the proteinaceous matrix of type I collagen and form a saucer-shaped lacuna along with resorption tunnels in the trabecular bone. Osteoblasts secrete a soluble decoy receptor, osteoprotegerin that prevents the binding of RANK/RANKL and thus moderating osteoclastogenesis. Moreover, bone homeostasis is also regulated by several growth factors like, cytokines, calciotropic hormones, parathyroid hormone and sex steroids. The current review presents a correlation of the probable molecular targets underlying the regulation of bone mass and the role of essential metabolic elements in bone remodelling. Targeting these signaling pathways may help to design newer therapies for treating bone diseases.

Abstract
Withaferin A (WA), a manifold studied, C28-steroidal lactone withanolide found in Withania somnifera. Given its unique beneficial effects, it has gathered attention in the era of modern science. Cancer, being considered a "hopeless case and the leading cause of death worldwide, and the available conventional therapies have many lacunae in the form of side effects. The poly pharmaceutical natural compound, WA treatment, displayed attenuation of various cancer hallmarks by altering oxidative stress, promoting apoptosis, and autophagy, inhibiting cell proliferation, reducing angiogenesis, and metastasis progression. The cellular proteins associated with antitumor pathways were also discussed. WA structural modifications attack multiple signal transduction pathways and enhance the therapeutic outcomes in various diseases. Moreover, it has shown validated pharmacological effects against multiple neurodegenerative diseases by inhibiting acetylcholesterinases and butyrylcholinesterases enzyme activity, antidiabetic activity by upregulating adiponectin and preventing the phosphorylation of peroxisome proliferator-activated receptors (PPARγ), cardioprotective activity by AMP-activated protein kinase (AMPK) activation and suppressing mitochondrial apoptosis. The current review is an extensive survey of various WA associated disease targets, its pharmacokinetics, synergistic combination, modifications, and biological activities.

Abstract
The bioaccessibility and bioavailability of a functionalized Calcium (Ca) salt as food ingredient, based on modified Ca carbonate and hydroxyapatite (FCC), was determined and compared with frequently used Ca sources (Ca citrate tetrahydrate (CCT), tri-Ca phosphate (triCP) and Ca carbonate (CC). Results showed a similar Ca bioaccessibility for CCT (76.44 ± 9.73%), CC (73.7 ± 8.18%) and FCC (74.4 ± 1.87%) and a lower value for tri-CP (46.07 ± 8.68%). FCC showed the highest bioavailability, 5.68 ± 0.26%, compared to CC, CCT and tri-CP (3.93 ± 0.99%, 3.41 ± 0.33%, 1.85 ± 0.34%, respectively). The innovative chemical composition and structure of FCC based on amorphous hydroxyapatite combined with Ca carbonate, a greater porosity, lower agglomerates and particle size, improve the Ca solubility in the intestinal media, explaining the similar bioaccessibility but higher bioavailability of FCC compared to CCT, tri-CP and CC.

Abstract
STUDY QUESTION Do human oocytes express voltage-gated proton channels? SUMMARY ANSWER Human oocytes exhibit voltage-gated proton currents. WHAT IS KNOWN ALREADY Voltage-gated proton currents have been reported in human sperm, where they contribute to capacitation and motility. No such studies of human oocytes exist. STUDY DESIGN, SIZE, DURATION Voltage-clamp studies were undertaken using entire oocytes and vesicles derived from oocytes and in excised patches of membrane from oocytes. PARTICIPANTS/MATERIALS, SETTING, METHODS Frozen, thawed human metaphase II oocytes were obtained from material donated to the gamete repository at the Rush Center for Advanced Reproductive Care. Prior to patch clamping, oocytes were warmed and equilibrated. Formation of an electrically tight seal requires exposing bare oolemma. Sections of the zona pellucida (ZP) were removed using a laser, followed by repeated pipetting, to further separate the oocyte from the ZP. Patch-clamp studies were performed using the whole-cell configuration on oocytes or vesicles derived from oocytes, and using inside-out patches of membrane, under conditions optimized to detect voltage-gated proton currents. MAIN RESULTS AND THE ROLE OF CHANCE Proton currents are present at significant levels in human oocytes where they exhibit properties similar to those reported in other human cells, as well as those in heterologous expression systems transfected with the HVCN1 gene that codes for the voltage-gated proton channel. LARGE SCALE DATA N/A. LIMITATIONS, REASONS FOR CAUTION Human oocytes are large cells, which limits our ability to control the intracellular solution. Subtle effects of cryopreservation by vitrification and subsequent warming on properties of HVCN1, the HVCN1 gene product, cannot be ruled out. WIDER IMPLICATIONS OF THE FINDINGS Possible functions for voltage-gated proton channels in human oocytes may now be contemplated. STUDY FUNDING/COMPETING INTEREST(S) NIH R35GM126902 (TED), Bears Care (DM). No competing interests. TRIAL REGISTRATION NUMBER N/A.

Abstract
Background:
β-amyloid (Aβ) production and aggregation is the main culprit of Alzheimer’s disease (AD). AD
is becoming crisis where no treatment available for halting the disease progression. Antibiotics are used not only to treat
infections, but also some of the non-contagious diseases and have found active as anti-amyloidogenic agents.
Objective:
The work aim’s to investigate anti-amyloidogenic activity of antibiotics as re-purposing agents via inhibiting
Aβ aggregation and fibril formation employing in-silico and in-vitro approaches.
Mehtods:
In-silico screening was designed with receptor and ligand preparation, grid formation, docking simulation and
its analysis. Thioflavin T-amyloid binding and protease-digestion studies were intended as in-vitro assays. The
pharmacological potential of antibiotics as anti-amyloidogenic agents was assessed by these methods.
Results:
Paromomycin and Neomycin were identified with higher order of estimated free energy of binding in in-silico
sreening. In in-vitro screening, paromomycin significantly (p<0.01) reduced the fluorescence intensity and resistance to
tryptic degradation of Aβ(1-42) peptides while neomycin had no or little effect (p<0.01) when compared to control.
Results from docking and wet lab studies were found in correlation.
Conclusion:
Paromomycin exhibited higher anti-Aβ aggregating and defibrillogenic activity than neomycin and leaves an
indication for further in-vivo testing and could be a future promising anti-amyloidal candidate for the treatment of several
amyloidoses.

Abstract
Non-ionic carbohydrate based gemini surfactants with rigid aromatic spacer CH2-Ar-CH2, which carry two hydrophobic tails of different tail lengths (C12, C14 and C16) and two sugar moiety polar head groups were synthesized and their reverse micellar behavior for solubilization of some aromatic α-amino acids viz. histidine (His), phenylalanine (Phy), tyrosine (Tyr) and tryptophan (Trp) in n-hexane were studied by spectroscopic analysis. The head group of these gemini surfactants consists of sugar moiety connected to C-6 of tertiary amines. Amino acids form complexes in order of His > Phy > Tyr > Trp, and in all cases it was found that the D-enantiomers solubilize better in comparison to the L-enantiomers. Moreover, more hydrophobic surfactants i.-e. surfactants with longer hydrocarbon tails show greater complex formation tendency towards D- and L-enantiomers of aromatic α-amino acids.

Abstract
Alzheimer's, a degenerative cause of the brain cells, is called as a progressive neurodegenerative disease and appears to have a heterogeneous etiology with main emphasis on amyloid-cascade and hyperphosphorylated tau-cascade hypotheses, that are directly linked with macromolecules called enzymes such as β- & γ-secretases, colinesterases, transglutaminases, and glycogen synthase kinase (GSK-3), cyclin-dependent kinase (cdk-5), microtubule affinity-regulating kinase (MARK). The catalytic activity of the above enzymes is the result of cognitive deficits, memory impairment and synaptic dysfunction and loss, and ultimately neuronal death. However, some other enzymes also lead to these dysfunctional events when reduced to their normal activities and levels in the brain, such as α- secretase, protein kinase C, phosphatases etc; metabolized to neurotransmitters, enzymes like monoamine oxidase (MAO), catechol-O-methyltransferase (COMT) etc. or these abnormalities can occur when enzymes act by other mechanisms such as phosphodiesterase reduces brain nucleotides (cGMP and cAMP) levels, phospholipase A2: PLA2 is associated with reactive oxygen species (ROS) production etc. On therapeutic fronts, several significant clinical trials are underway by targeting different enzymes for development of new therapeutics to treat Alzheimer's, such as inhibitors for β-secretase, GSK-3, MAO, phosphodiesterase, PLA2, cholinesterases etc, modulators of α- & γ-secretase activities and activators for protein kinase C, sirtuins etc. The last decades have perceived an increasing focus on findings and search for new putative and novel enzymatic targets for Alzheimer's. Here, we review the functions, pathological roles, and worth of almost all the Alzheimer's associated enzymes that address to therapeutic strategies and preventive approaches for treatment of Alzheimer's.

Abstract
BACKGROUND Patients with knee osteoarthritis may undergo total knee replacement too early or may delay or underuse this procedure. We quantified these categories of total knee replacement utilization in 2 cohorts of participants with knee osteoarthritis and investigated factors associated with each category. METHODS Data were pooled from 2 multicenter cohort studies that collected demographic, patient-reported, radiographic, clinical examination, and total knee replacement utilization information longitudinally on 8,002 participants who had or were at risk for knee osteoarthritis and were followed for up to 8 years. Validated total knee replacement appropriateness criteria were longitudinally applied to classify participants as either potentially appropriate or likely inappropriate for total knee replacement. Participants were further classified on the basis of total knee replacement utilization into 3 categories: timely (indicating that the patient had total knee replacement within 2 years after the procedure had become potentially appropriate), potentially appropriate but knee not replaced (indicating that the knee had remained unreplaced for >2 years after the procedure had become potentially appropriate), and premature (indicating that the procedure was likely inappropriate but had been performed). Utilization rates were calculated, and factors associated with each category were identified. RESULTS Among 8,002 participants, 3,417 knees fulfilled our inclusion and exclusion criteria and were classified into 1 of 3 utilization categories as follows: 290 knees (8% of the total and 9% of the knees for which replacement was potentially appropriate) were classified as "timely", 2,833 knees (83% of the total and 91% of those for which replacement was potentially appropriate) were classified as "potentially appropriate but not replaced", and 294 knees (comprising 9% of the total and 26% of the 1,114 total knee replacements performed) were considered to be "likely inappropriate" yet underwent total knee replacement and were classified as "premature". Of the knees that were potentially appropriate but were not replaced, 1,204 (42.5%) had severe symptoms. Compared with the patients who underwent timely total knee replacement, the likelihood of being classified as potentially appropriate but not undergoing total knee replacement was greater for black participants and the likelihood of having premature total knee replacement was lower among participants with a body mass index of >25 kg/m and those with depression. CONCLUSIONS In 2 multicenter cohorts of patients with knee osteoarthritis, we observed substantial numbers of patients who had premature total knee replacement as well as of patients for whom total knee replacement was potentially appropriate but had not been performed >2 years after it had become potentially appropriate. Further understanding of these observations is needed, especially among the latter group. CLINICAL RELEVANCE Undergoing total knee replacement too early may result in little or no benefit while exposing the patient to the risks of a major operation, whereas waiting too long may cause limitations in physical activity that in turn increase the risk of additional disability and chronic disease; however, little is known about timing of this surgery. We quantified the extent of premature, timely, and delayed use, and found a high prevalence of both premature and delayed use.

Abstract
OBJECTIVE To develop a model of early osteoarthritis, by examining whether radiographically normal knees with contralateral joint space narrowing (JSN), but without contralateral trauma history, display greater longitudinal cartilage composition change (transverse relaxation time; T2) than subjects with bilaterally normal knees. METHODS 120 radiographically normal knees (Kellgren Lawrence grade [KLG] 0) from the Osteoarthritis Initiative were studied. 60 case knees displayed definite contralateral radiographic knee osteoarthritis (KLG ≥ 2) whereas 60 reference subjects were bilaterally KLG0, and were matched 1:1 to cases based on age, sex, and BMI. All had multi-echo spin-echo MRI acquired at year (Y) 1 and 4 follow-up, with cartilage T2 being determined in superficial and deep cartilage layers across 16 femorotibial subregions. T2 across all regions was considered the primary analytic focus. RESULTS Of 60 KLG0 case knees (30 female, age: 65.0 ± 8.8 y, BMI: 27.6 ± 4.4 kg/m2), 21/22/13/4 displayed contralateral JSN 0/1/2/3, respectively. The longitudinal increase in the deep layer cartilage T2 between Y1 and Y4 was significantly greater (P = 0.03; Cohen's D 0.50) in the 39 KLG0 case knees with contralateral JSN (1.2 ms; 95% confidence interval [CI] [0.4, 2.0]) than in matched KLG0 reference knees (0.1 ms; 95% CI [-0.5, 0.7]). No significant differences were identified in superficial T2 change. T2 at Y1 was significantly greater in case than in reference knees, particularly in the superficial layer of the medial compartment. CONCLUSIONS Radiographically normal knees with contralateral, non-traumatic JSN represent an applicable model of early osteoarthritis, with deep layer cartilage composition (T2) changing more rapidly than in bilaterally normal knees.

Abstract
Gemini surfactants (gemini) are a distinct class of amphiphiles having more than one hydrophobic tail and hydrophilic head group connected via a spacer. These surfactants usually have better surface active properties than corresponding conventional surfactant of equal chain length. Depending upon the nature of charge on head group, these geminis may be cationic or anionic. If there is no charge on head group, the geminis are termed as non-ionic. Carbohydrate derived gemini surfactants carry sugar moiety linked with each of the conventional surfactants, which are further connected by spacer. The sugar moiety was found to enhance the aggregation tendencies. Moreover, due to the presence of sugar moiety, these surfactants are non-toxic and biodegradable. Due to chiral nature of sugar moiety, these surfactants can be used for chiral recognition of some chiral drugs in order to improve their aqueous solubility. Non-ionic surfactants are more important than ionic surfactants as in the latter case, due to repulsion among the same charged head group, aggregation does not take place readily. However, in case of non-ionic surfactants, the head group carries no charge, so there is no repulsion, thus micelle forms easily and at low concentration. The only repulsive forces among head groups are due to hydration shell formed by solvent molecules.

Abstract
OBJECTIVE To test whether radiographically normal knees with contralateral radiographic knee osteoarthritis (OA), but without contralateral trauma history, display greater cartilage thickness loss than knees from subjects with bilaterally radiographically normal knees. METHODS 828 radiographically normal knees (Kellgren Lawrence grade [KLG] 0) from the Osteoarthritis Initiative [OAI] were studied; 150 case knees displayed definite radiographic knee OA (KLG ≥ 2) contralaterally, and had MRI double echo steady state (DESS) images available at 12 and 48 month follow-up. 678 reference knees displayed KLG0 at the contralateral side. Cartilage thickness change was determined in femorotibial subregions and location-independent cartilage thinning scores were computed. Case and reference knees were compared using ANCOVA. RESULTS Of the 150 KLG0 case knees, 108 had a contralateral KLG2 knee (50 without, and 58 with joint space narrowing [JSN]), 31 a KLG3 and 11 a KLG4 knee. The cartilage thinning score tended to be greater in case than reference knees; the cartilage thinning score in KLG0 case knees with contralateral radiographic JSN (-858 μm; [95% confidence interval -1016, -701 μm]) was significantly greater (P = 0.0012) than that in bilaterally KLG0 reference knees (-634 μm; [-673, -596 μm]), whereas KLG0 knees with contralateral KLG2 without JSN only showed relatively small thinning scores (-530 μm, [-631, -428 μm]). Region-specific analysis suggested greater rates of cartilage loss in case than in reference knees in the lateral, rather than medial, femorotibial compartment. CONCLUSIONS Radiographically normal knees with contralateral JSN may serve as a human model of early OA, for testing disease modifying drugs in clinical trials designed to prevent cartilage loss before the onset of radiographic change.

Abstract
Purpose: To evaluate clinical outcomes and failure patterns in patients with locally
advanced cervical cancer (LACC) treated definitively using image-guided
volumetric-modulated arc therapy (IG-VMAT). Methods and materials: This retrospective review included 18 consecutively treated patients with
LACC. Treatment consisted of IG-VMAT and concurrent chemotherapy followed by
intracavitary radiotherapy. The primary end points were overall survival
(OS) and disease-free survival (DFS). Acute haematologic toxicity was
evaluated using Radiation Therapy Oncology Group (RTOG) criteria. Results: A total of 16 patients were either stage IIB or IIIB and the median follow-up
was 30.5 months (interquartile range: 13-36.25 months). The 2-year DFS was
63.3% (95% confidence interval [CI]: 52.8%-72.4%) and 2-year OS was 72.2%
(95% CI: 62.1%-80.5%). There were 7 treatment failures, predominantly
in-field. Acute haematologic toxicity was low. Conclusions: IG-VMAT is associated with favourable outcomes for patients with LACC.
