Abstract
Major Depressive Disorder (MDD) is one of the leading causes of disability affecting more than 340 million people and second largest contributor to global burden of disease. Chronic stress is a common risk factor and important contributor for MDD. Stress could be defined as the "perceived inability to cope". Stressful life events are shown to provoke a sequence of psychological and physiological adjustments including nervous, endocrine and immune mechanisms. Stress can lead to elevation of a variety of inflammatory cytokines and stress hormones, can cause autonomic dysfunction and imbalance in neurotransmitters. Yoga can reduce depressive symptoms by alleviating stress. Studies have shown that yoga can reduce inflammation, maintain autonomic balance and also has a role in maintaining the neurotransmitters. It has role on hypothalamic-pituitary-adrenal (HPA) axis, the peripheral nervous system including GABA, limbic system activity, inflammatory and endocrine responses. Yoga along with antidepressants can help in reducing the depressive symptoms in patient with MDD. Yoga is an ideal complementary and alternative therapy for mental health disorders.

Abstract
IMPORTANCE Hypertension is the modifiable risk factor associated with cardiovascular diseases and all-cause mortality. Foot reflexology has been proposed to reduce the blood pressure for the patients with hypertension but the available evidences are uncertain. OBJECTIVE We conducted a systematic review and meta-analysis, know the efficacy of foot reflexology on blood pressure reduction in patients with hypertension. DATA SOURCES AND SELECTION A systematic search of electronic databases such as PubMed, Scopus, ClinicalTrials.gov, Embase, and Cochrane library since inception till January 2022. Randomized controlled trial with foot reflexology as an intervention for lowering blood pressure (BP) in hypertensive patients was included in the study. DATA EXTRACTION AND OUTCOME MEASURES Data was independently extracted by four authors. Systolic and diastolic blood pressure was the primary outcome measure. Standardized mean difference (SMD) and 95 % confidence interval (CI) were calculated to determine the effect size. RESULTS The pooled effect of SBP (SMD: -2.70, 95 % of CI: -6.79, 1.39, I2 - 97 %, P < 0.001) and DBP (SMD: -2.12, 95 % of CI: -5.95, 1.71, I2 - 97 %, P < 0.001) changes are not favorable for foot reflexology in terms of reducing blood pressure. CONCLUSION Findings from the studies showed that foot reflexology interventions were not much effective in the reduction of blood pressure among patients with hypertension.

Abstract
Topical minoxidil is used for treating different hair disorders. Even though it is an effective therapy, many patients show poor compliance due to the cost, side effects, and duration of treatment. Topical minoxidil is the mainstay treatment for androgenetic alopecia (AGA). Recently, low alcohol or alcohol-free topical minoxidil formulation has proven to be an alternative for patients suffering from AGA, including those with poor compliance with other therapies. Thus, the current article provides the positioning of low alcohol or alcohol-free topical minoxidil to manage AGA in Indian clinical practice.

Abstract
BACKGROUND Diabetes mellitus has a significant impact on public health. Oxidative stress plays a major role in the pathophysiology of Type 2 Diabetes Mellitus (T2DM), leading to various complications of T2DM. Yoga is being widely used in the management of T2DM. The primary objective of this systematic review and meta-analysis is to understand the effects of yoga on oxidative stress parameters among adult patients diagnosed with T2DM. MATERIALS AND METHODS Electronic databases such as PubMed, Scopus, Cochrane Library and Science Direct from start of the study till March 2020 were searched to obtain eligible studies. Study designs of all nature were included (except case studies and reviews). The primary outcome was Malondialdehyde (MDA) and secondary outcomes included fasting plasma glucose, HbA1C and Superoxide Dismutase (SOD) levels. RESULTS A total of four trials with a total of 440 patients met the inclusion criteria. The results of meta-analysis indicated that yoga significantly reduced MDA (SMD: -1.4; 95% CI -2.66 to -0.13; P = 0.03; I2 = 97%), fasting plasma glucose levels (SMD: -1.87: 95% CI -3.83 to -0.09; P = 0.06; I2= 99%), and HbA1c (SMD: -1.92; 95% CI - 3.03 to -0.81; P = 0.0007; I2 = 92%) in patients with T2DM. No such effect was found for SOD (SMD: -1.01; 95% CI -4.41 to 2.38; P = 0.56; I2= 99%). CONCLUSION The available evidence suggests that yoga reduces MDA, fasting plasma glucose and HbA1C, and thus would be beneficial in the management of T2DM as a complementary therapy. However, considering the limited number of studies and its heterogeneity, further robust studies are necessary to strengthen our findings and investigate the long-term benefits of yoga.

Abstract
BACKGROUND A combination of yoga practices has been documented to reduce stress and stress-induced cortisol levels. The objective of the current study is to examine the effects of six months of a single pranayama practice (Bhramari [Bhr. P]) on reducing salivary cortisol response to the cold pressor test (CPT) among adolescents. METHODS Twenty-six healthy adolescents between the ages of 11 and 19 were randomly assigned to either yoga group (n-13) or control group (n-13). Yoga group participants were trained to do Bhr. P for 45 min, thrice a week for six months. All participants underwent CPT at baseline and at end of six months. Saliva samples were collected at baseline (t0), at 20 min (t1), 40 min (t2), and 60 min after the CPT (t3). RESULTS Contradictory to our hypothesis, participants in the yoga group exhibited a higher salivary cortisol response to the CPT at t1 (p = 0.04) when compared to the control group. However, the t3 salivary cortisol levels showed a statistically significant reduction (p = 0.03) in yoga group when compared to the control group. A significant interaction with time (F (1, 88) = 316.5, p = .001, ηp2:0.91) and between the group × time (F (3, 88) = 2.83, p = 0.04, ηp2:0.8) was found after the intervention. CONCLUSIONS An increase in the cortisol responsiveness observed in the study is an indication of the adaptive capability achieved through regular yoga training, evidenced by an initial rise in cortisol followed by a rapid fall below baseline after 60 min. Further research is required to conclusively determine the changes in cortisol levels over time in response to stress in long-term yoga practitioners.

Abstract
The seafood industry generates large volumes of waste. These include processing discards consisting of shell, head, bones intestine, fin, skin, voluminous amounts of wastewater discharged as effluents, and low-value under-utilized fish, which are caught as by-catch of commercial fishing operations. The discards, effluents, and by-catch are rich in nutrients including proteins, amino acids, lipids containing good proportions of polyunsaturated fatty acids (PUFA), carotenoids, and minerals. The seafood waste is, therefore, responsible for loss of nutrients and serious environmental hazards. It is important that the waste is subjected to secondary processing and valorization to address the problems. Although chemical processes are available for waste treatment, most of these processes have inherent weaknesses. Biological treatments, however, are environmentally friendly, safe, and cost-effective. Biological treatments are based on bioconversion processes, which help with the recovery of valuable ingredients from by-catch, processing discards, and effluents, without losing their inherent bioactivities. Major bioconversion processes make use of microbial fermentations or actions of exogenously added enzymes on the waste components. Recent developments in algal biotechnology offer novel processes for biotransformation of nutrients as single cell proteins, which can be used as feedstock for the recovery of valuable ingredients and also biofuel. Bioconversion options in conjunction with a bio-refinery approach have potential for eco-friendly and economical management of seafood waste that can support sustainable seafood production.

Abstract
OBJECTIVES Steam bath is extensively used around the world. However, its physiological influence is not understood in detail. Objective of the current study is to examine the effects of 12 sessions of steam bath on spirometric parameters among healthy participants. METHODS Forty healthy adult volunteers of both sex (14 male and 26 female) aged 26.38 ± 8 years participated in the study. A steam bath session (10-15 min) was given once a week for 12 weeks. The spirometric parameters [forced expiratory volume in the 1st second (FEV1, L), forced vital capacity (FVC, L), FEV1/FVC ratio (absolute value), maximal mid-expiratory flow (MMEF, L/s) and peak expiratory flow (PEF, L/s)] were measured by Helios 401 spirometer. RESULTS Compared to baseline, post-intervention spirometric parameters showed significant (p<0.05) improvement in the FVC (82.40 ± 11.24 to 96.91 ± 18.76), FEV1 (86.13 ± 14.39 to 91.17 ± 12.48), FEV1/FVC ratio (86.96 ± 3.64 to 93.75 ± 4.80), MMEF 25-75% (86.96 ± 3.64 to 94.16 ± 11.57), peak expiratory flow rate (79.82 ± 14.90 to 92.18 ± 18.96). CONCLUSIONS Taking steam bath improves the spirometric parameters of healthy adult participants. However, future randomized controlled trials with on a large scale have to done to validate our findings.

Abstract
The forecast of Indian monsoon droughts has been predicated on the notion of a season-long rainfall deficit linked to a warm equatorial Pacific. Here we show that nearly half of all droughts over the past century differ from this paradigm in that they (i) occur when Pacific temperatures are near-neutral and (ii) are subseasonal phenomena, characterized by an abrupt decline in late-season rainfall. This severe subseasonal rainfall deficit can be associated with a Rossby wave from mid-latitudes. Specifically, we find that the interaction of upper-level winds with an episodic North Atlantic vorticity anomaly results in a wavetrain that curves toward East Asia, disrupting the monsoon. This atmospheric teleconnection offers an avenue for improved predictability of droughts, especially in the absence of telltale signatures in the Pacific.

Abstract
Background:
Spread of COVID-19 attains a crucial transition in reveling its pandemic across
the boundaries. In combating the infection caused by SARS-CoV-2, there is a spectrum of ideal strategies
that have been adopted globally, of which repurposing of approved drugs considerably having high
clinical relevance. 3-chymotrypsin-like protease (3CL pro) is considered to be the potential target for the
researchers as it is highly essential for cleavage of polyprotein to get 16 nonstructural proteins (called
nsp1-nsp16). These proteins are highly essential for viral replication and hence become a primary target
for enzyme inhibitors. 3CL pro, having a structural projectile helical chain with biologically active site
involved in processing viral polyproteins that are evolved from RNA genome translation.
Objective:
The major objective of the present investigation is to evaluate the enzyme inhibition potential
of FDA approved therapeutic leads in targeting 3CLpro that medicates the viral replication.
Methods:
Docking calculations were carried out for an array of FDA approved molecules which leads to
a notable few molecules such as Emtricitabine, Oseltamivir, Ganciclovir, Chloroquine, Baricitinib,
Favipiravir, Lopinavir, Ritonavir, Remdesivir, Ribavirin, Tenofovir, Umifenovir, Carbapenam, Ertapenem
and Imipenam which have both specificity and selectivity in terms of binding efficiency against
3CL proenzyme.
Results:
A combinatorial evaluation employing in-silico screening shows a major lead for remdesivir
which possesses a substantial affinity to 3CL pro binding on core amino acid residues, such as Leu 27,
His 41, Gly 143, Cys 145, His 164, Met 165, Glu 166, Pro 168 and His 172 which share the biological
significance in mediating enzymatic action. Results of docking simulation by Autodock over a host of
FDA approved molecules show high degree of selectivity and specificity in the increasing order of binding
capacity; Remdesivir> Ertapenem> Imipenam> Tenofovir> Umifenovir> Chloroquine> Lopinavir>
Ritonavir> Emtricitabine> Ganciclovir> Baricitinib> Ribavirin>Oseltamivir>Favipiravir> Carbapenam.
Conclusion:
Till date, there is no known cure attained for treating COVID-19 infection. In conclusion,
lead molecules from already approved sources provoke promising potential which grabs the attention of
the clinicians in availing potential therapeutic candidate as a drug of choice in the clinical management
of COVID-19 time-dependently.

Abstract
Abstract:
The pandemic spread of severe acute respiratory syndrome coronavirus (SARS-CoV-2)
that causes COVID-19 calls for global health emergency with wide prevalence across 94 countries,
and around 3073 deaths reported in china on 7th March 2020 which created red alert zone in the
country. It was further noticed other than China, countries like the republic of Korea ranked first
with 6767 cases, Italy with 4747 and Iran with 3513 cases. The spread of COVID-19 made a
historical transition between December 2019 to March 2020 by extending the paradigm to a newer
territory every day with the highest predicted reproductive number <2. Hence, while combating the
epidemic spread, there are spectra of strategies that require crucial validation, some of which include
drug repurposing, enzyme inhibition, target drug delivery etc. Among these, the category of drugs
called enzyme inhibitors has a unique opportunity in the process of new drug discovery as these
enzymes possess structural versatility starting from the host viral interface and up to the release of a
new virus. Drugs entrapped within liposomes are highly effective against intracellular
microorganisms as per published observations. Regulatory authorities like World Health
Organization (WHO) and Centre for disease control and prevention (CDC) strongly recommend the
need for the PPE’s like N95 respirator to avoid person to person contact. In this context, Electrospun
Nanofiber Technology (ENT) offers ultrathin fibres (20-200 nm) with close proximity of 99.97% of
high efficient air filtration. Fabrication of ultrafine nano mask by utilizing electospun technology
will surely benefit millions of people in a time-dependent manner.

Abstract
Experimental data was obtained in order to investigate the effect of waves on the loads and performance of tidal turbines. An instrumented 1:15 scale tidal turbine was installed in the FloWave Ocean Energy Research Facility, and a wide range of regular wave conditions were generated; systematically varying both wave frequency and height. Waves were generated both following and opposing a fixed mean current velocity of 0.81 m/s. Data are made available of the measured turbine loads and environmental conditions obtained for five repeats of 24 wave conditions via https://doi.org/10.7488/ds/2472. A description of the data collection process, data processing, file structure and naming conventions are provided in this article. The analysis and presentation of the described dataset can be found in Ref. [1].

Abstract
BACKGROUND PBSC collection using apheresis is the preferred source of hematopoietic stem cells transplantation. However, apheresis procedures fail to harvest adequate CD34 yield in 5 to 40% of patients during the first collection. Therefore, this study aimed to study both the clinical- and equipmentrelated factors influencing CD34 yield among the autologous patients and to compare the collection efficiency of two apheresis equipments(Haemonetics MCS+ and Terumo Spectra Optia). METHODS Retrospective analysis of 69 patients underwent PBSC collection from 2015 to 2018. Frequency, clinical- and equipment-related factors responsible for adequate CD34+ cells (≥2 x106 cells/kg) yield during the first collection was studied. Factors such as collection efficiency, percentage platelet loss and percentage hemoglobin loss were considered to compare the two apheresis system. RESULTS Two-third (72%) patients of the study population had adequate CD34 stem cells yield during the first collection. Factors such as exposure to lenalidomide-based pretreatment regimen, peripheral blood WBC count and CD34 count are associated with the adequate CD34 yield. Optia had a slightly better collection efficiency than MCS+ (50 and 44; p=0.37). Optia had lower product volume (237 vs 298 ml) and lesser procedure duration (277 vs 360 min), whereas the median Hb loss (3.0% and 2.3%) and mean platelet loss (49% and 34%) were higher with MCS. CONCLUSION This study infers that the collection efficiency of both the equipments in collecting CD34 stem cells was similar. However, during PBSC collection, procedures using Optia can be preferred to MCS+ on the patients with risk of anemia and thrombocytopenia.

Abstract
Suicide remains a clear, present and increasing public health problem, despite being a potentially preventable tragedy. Its incidence is particularly high in people with overt or un(der)diagnosed psychiatric disorders. Objective and precise identification of individuals at risk, ways of monitoring response to treatments and novel preventive therapeutics need to be discovered, employed and widely deployed. We sought to investigate whether blood gene expression biomarkers for suicide (that is, a 'liquid biopsy' approach) can be identified that are more universal in nature, working across psychiatric diagnoses and genders, using larger cohorts than in previous studies. Such markers may reflect and/or be a proxy for the core biology of suicide. We were successful in this endeavor, using a comprehensive stepwise approach, leading to a wealth of findings. Steps 1, 2 and 3 were discovery, prioritization and validation for tracking suicidality, resulting in a Top Dozen list of candidate biomarkers comprising the top biomarkers from each step, as well as a larger list of 148 candidate biomarkers that survived Bonferroni correction in the validation step. Step 4 was testing the Top Dozen list and Bonferroni biomarker list for predictive ability for suicidal ideation (SI) and for future hospitalizations for suicidality in independent cohorts, leading to the identification of completely novel predictive biomarkers (such as CLN5 and AK2), as well as reinforcement of ours and others previous findings in the field (such as SLC4A4 and SKA2). Additionally, we examined whether subtypes of suicidality can be identified based on mental state at the time of high SI and identified four potential subtypes: high anxiety, low mood, combined and non-affective (psychotic). Such subtypes may delineate groups of individuals that are more homogenous in terms of suicidality biology and behavior. We also studied a more personalized approach, by psychiatric diagnosis and gender, with a focus on bipolar males, the highest risk group. Such a personalized approach may be more sensitive to gender differences and to the impact of psychiatric co-morbidities and medications. We compared testing the universal biomarkers in everybody versus testing by subtypes versus personalized by gender and diagnosis, and show that the subtype and personalized approaches permit enhanced precision of predictions for different universal biomarkers. In particular, LHFP appears to be a strong predictor for suicidality in males with depression. We also directly examined whether biomarkers discovered using male bipolars only are better predictors in a male bipolar independent cohort than universal biomarkers and show evidence for a possible advantage of personalization. We identified completely novel biomarkers (such as SPTBN1 and C7orf73), and reinforced previously known biomarkers (such as PTEN and SAT1). For diagnostic ability testing purposes, we also examined as predictors phenotypic measures as apps (for suicide risk (CFI-S, Convergent Functional Information for Suicidality) and for anxiety and mood (SASS, Simplified Affective State Scale)) by themselves, as well as in combination with the top biomarkers (the combination being our a priori primary endpoint), to provide context and enhance precision of predictions. We obtained area under the curves of 90% for SI and 77% for future hospitalizations in independent cohorts. Step 5 was to look for mechanistic understanding, starting with examining evidence for the Top Dozen and Bonferroni biomarkers for involvement in other psychiatric and non-psychiatric disorders, as a mechanism for biological predisposition and vulnerability. The biomarkers we identified also provide a window towards understanding the biology of suicide, implicating biological pathways related to neurogenesis, programmed cell death and insulin signaling from the universal biomarkers, as well as mTOR signaling from the male bipolar biomarkers. In particular, HTR2A increase coupled with ARRB1 and GSK3B decreases in expression in suicidality may provide a synergistic mechanistical corrective target, as do SLC4A4 increase coupled with AHCYL1 and AHCYL2 decrease. Step 6 was to move beyond diagnostics and mechanistical risk assessment, towards providing a foundation for personalized therapeutics. Items scored positive in the CFI-S and subtypes identified by SASS in different individuals provide targets for personalized (psycho)therapy. Some individual biomarkers are targets of existing drugs used to treat mood disorders and suicidality (lithium, clozapine and omega-3 fatty acids), providing a means toward pharmacogenomics stratification of patients and monitoring of response to treatment. Such biomarkers merit evaluation in clinical trials. Bioinformatics drug repurposing analyses with the gene expression biosignatures of the Top Dozen and Bonferroni-validated universal biomarkers identified novel potential therapeutics for suicidality, such as ebselen (a lithium mimetic), piracetam (a nootropic), chlorogenic acid (a polyphenol) and metformin (an antidiabetic and possible longevity promoting drug). Finally, based on the totality of our data and of the evidence in the field to date, a convergent functional evidence score prioritizing biomarkers that have all around evidence (track suicidality, predict it, are reflective of biological predisposition and are potential drug targets) brought to the fore APOE and IL6 from among the universal biomarkers, suggesting an inflammatory/accelerated aging component that may be a targetable common denominator.

Abstract
OBJECTIVE The objective of this study was to compare the effects of increased saturated fatty acid (SFA) (provided by fresh coconut) versus monounsaturated fatty acid (MUFA) intake (provided by a combination of groundnuts and groundnut oil) on plasma lipids and erythrocyte fatty acid (EFA) composition in healthy adults. MATERIAL AND METHODS Fifty-eight healthy volunteers, randomized into 2 groups, were provided standardized diet along with 100 g fresh coconut or groundnuts and groundnut oil combination for 90 days in a Yoga University. Fasting blood samples were collected before and after the intervention period for the measurement of plasma lipids and EFA profile. RESULTS Coconut diet increased low-density lipoprotein (LDL) and high-density lipoprotein (HDL) levels significantly. In contrast, the groundnut diet decreased total cholesterol (TC), mainly due to a decrease in HDL levels. There were no differences in the major SFA of erythrocytes in either group. However, coconut consumption resulted in an increase in C14:0 and C24:0 along with a decrease in levels of C18:1 n9 (oleic acid). There was a significant increase in levels of C20:3 n6 (dihomo-gamma linolenic acid, DGLA). CONCLUSIONS Consumption of SFA-rich coconut for 3 months had no significant deleterious effect on erythrocytes or lipid-related factors compared to groundnut consumption. On the contrary, there was an increase in the anti-atherogenic HDL levels and anti-inflammatory precursor DGLA in erythrocyte lipids. This suggests that coconut consumption may not have any deleterious effects on cardiovascular risk in normal subjects.

Abstract
Ocean waves have multidirectional components. Most wave measurements are taken at a single point, and so fail to capture information about the relative directions of the wave components directly. Conventional means of directional estimation require a minimum of three concurrent time series of measurements at different spatial locations in order to derive information on local directional wave spreading. Here, the relationship between wave nonlinearity and directionality is utilized to estimate local spreading without the need for multiple concurrent measurements, following Adcock & Taylor (Adcock & Taylor 2009 Proc. R. Soc. A465, 3361–3381. (doi:10.1098/rspa.2009.0031)), with the assumption that directional spreading is frequency independent. The method is applied to measurements recorded at the North Alwyn platform in the northern North Sea, and the results compared against estimates of wave spreading by conventional measurement methods and hindcast data. Records containing freak waves were excluded. It is found that the method provides accurate estimates of wave spreading over a range of conditions experienced at North Alwyn, despite the noisy chaotic signals that characterize such ocean wave data. The results provide further confirmation that Adcock and Taylor's method is applicable to metocean data and has considerable future promise as a technique to recover estimates of wave spreading from single point wave measurement devices.

Abstract
Commercial fishery processing results in discards up to 50% of the raw material, consisting of scales, shells, frames, backbones, viscera, head, liver, skin, belly flaps, dark muscle, roe, etc. Besides, fishing operations targeted at popular fish and shellfish species also result in landing of sizeable quantity of by-catch, which are not of commercial value because of their poor consumer appeal. Sensitivity to rapid putrefaction of fishery waste has serious adverse impact on the environment, which needs remedial measures. Secondary processing of the wastes has potential to generate a number of valuable by-products such as proteins, enzymes, carotenoids, fat, and minerals, besides addressing environmental hazards. Fishery wastes constitute good sources of enzymes such as proteases, lipases, chitinase, alkaline phosphatase, transglutaminase, hyaluronidase, acetyl glycosaminidase, among others. These enzymes can have diverse applications in the seafood industry, which encompass isolation and modification of proteins and marine oils, production of bioactive peptides, acceleration of traditional fermentation, peeling and deveining of shellfish, scaling of finfish, removal of membranes from fish roe, extraction of flavors, shelf life extension, texture modification, removal of off-odors, and for quality control either directly or as components of biosensors. Enzymes from fish and shellfish from cold habitats are particularly useful since they can function comparatively at lower temperatures thereby saving energy and protecting the food products. Potentials of these applications are briefly discussed.

Abstract
The Al-Ni phase diagram has been investigated in the com position range xNi = 0.70 to 0.97. Phase boundaries were determined by using differential thermal analysis and Knudsen effusion mass spectrometry. The measurements were carried out in the temperature range between 1409 and 1730K. An Al-Ni phase diagram is obtained for xNi ≧ 0.70 by combining the data from this work with selected data from the literature. This diagram deviates from that recommended by phase diagram compilations and used generally in the literature to date; it agrees reasonably well with a diagram which has been rejected in the literature.

Abstract
Acute hemorrhagic leukoencephalitis (AHLE, Hurst's disease) is a rare hyperacute variant of acute disseminated encephalomyelitis (ADEM) characterized by severe, rapidly progressive clinical illness and hemorrhagic necrosis of white matter. Like ADEM, it is often preceded by viral illness or vaccination. Plasmodium vivax infection is usually uncomplicated and non-fatal with only a handful of reports of central nervous system complications. In this article, we report a previously unknown association between AHLE and P. vivax infection.

Abstract
We report a case of a 60-year old unmarried male who presented with multiple ulcers and foul smelling discharge from the groin since 4 months and multiple tense bullae over the trunk of 1 month duration. Groove sign was present. Investigations for lymphogranuloma venereum (LGV) and other sexually transmitted diseases were negative. Histopathology from the ulcer in the groin and growth in the penis revealed squamous cell carcinoma (SCC). Skin biopsy of bulla was diagnostic of bullous pemphigoid (BP). We report a rare case of SCC masquerading as LGV with BP occurring as a paraneoplastic phenomenon.

Abstract
Woolly hair nevus is a rare non-hereditary focal condition characterized by unruly and tightly coiled hair. It can appear in childhood or adolescence and may be associated with epidermal or melanocytic nevus. Patients presenting with woolly hair must be examined completely to rule out cardiofaciocutaneous and Noonan syndrome.

Abstract
Secondary lymphangiomas or acquired lymphangiomas of vulva represent dilatation of upper dermal lymphatics following damage to previously normal deep lymphatics. They have been reported to occur following various infections, surgeries and radiotherapy which can cause damage to deep lymphatics.Treatment options in the management of secondary lymphangiomas include surgical resection, carbon dioxide laser vaporisation, sclerosing agents etc. We report two cases of secondary lymphangioma of vulva that followed radiotherapy for carcinoma of cervix. Both the patients were treated successfully by surgery.

Abstract
We have investigated ethene and oxygen co-adsorption on Cu(410) by high resolution electron energy loss spectroscopy. We find that these two species compete for the adsorption sites and that pre-exposure to oxygen affects ethene adsorption more or less strongly depending on oxygen coverage and the kind of occupied sites. The c(2 × 2) O overlayer is inert with respect to ethene adsorption, while when some oxygen is removed by thermally induced subsurface incorporation, ethene chemisorption is restored. The latter species also adsorbs on the disordered oxygen phase formed when O(2) is dosed at low crystal temperature. Contrary to the bare surface case, most of the ethene ends up in a π-bonded configuration. Dehydrogenation occurs, too, albeit as a minority channel. The so-produced carbon reacts already at low temperature with adsorbed oxygen to yield carbon monoxide, which desorbs around 190 K.

Abstract
Abstract
This paper describes an electrochemical method for the preparation of 57Co source to be used in quality evaluation of nuclear fuel rods. The electrolytic cell, the experimental set up used and the process of deposition are described. The effect of various parameters such as pH of the electrolyte, bath temperature, current density, content of cobalt in the bath, electrolyte volume in the cell and deposition time were investigated and optimized for maximum deposition. The texture and morphology of the electrodeposited samples were examined by X-ray diffraction (XRD), SEM and EDS analyses. Sources containing ∼370 MBq (10 mCi) 57Co on a circular copper foil of 4 mm diameter could be prepared and encapsulated in an aluminum capsule. Quality assurance tests performed to ensure non-leachability, uniform distribution of activity and stability of the sources gave satisfactory results.
