Abstract
ABSTRACT There is an understandable concern that obsessive-compulsive disorder (OCD) may worsen during the COVID-19 pandemic, but there are little empirical data. We report the impact of COVID-19 pandemic on the short-term course of OCD. A cohort of patients with a primary diagnosis of OCD (n = 240) who were on regular follow-up at a tertiary care specialty OCD clinic in India were assessed telephonically, about 2 months after the declaration of the pandemic ("pandemic" cohort). Data from the medical records of an independent set of patients with OCD (n = 207) who were followed up during the same period, 1 year prior, was used for comparison (historical controls). The pandemic group and historical controls did not differ in the trajectories of the Yale-Brown Obsessive-Compulsive Scale scores (chi-square likelihood ratio test of the group × time interaction = 2.73, p = 0.255) and relapse rate (21% vs. 20%; adjusted odds ratio, 0.81; 95% confidence interval, 0.41-1.59; p = 0.535). Preexisting contamination symptoms and COVID-19-related health anxiety measured by the COVID-Threat Scale did not predict relapse. Only a small proportion of patients (6%) reported COVID-19-themed obsessive-compulsive symptoms. The COVID-19 pandemic, at least in the short run, did not influence the course of illness.

Abstract
Chlorpromazine is a low potency "typical" antipsychotic agent used to treat schizophrenia. It continues to be prescribed frequently in India owing to its lower cost. There have been previous reports of ocular adverse effects with prolonged use of chlorpromazine. We report three patients who developed corneal and lenticular opacities secondary to prolonged chlorpromazine use leading to visual impairment. Early detection of ocular deposits and switching over to risperidone from chlorpromazine helped in the reversal of chlorpromazine- induced ocular side effects in one of them. The case series further adds evidence to the causative relationship between chlorpromazine and ocular side effects.

Abstract
Abnormalities in resting and event-related brain oscillations are known to be associated with cognitive deficits in schizophrenia. Transcranial alternating current stimulation (tACS) modulates these rhythms across the neuronal circuits and could have a potential therapeutic role in psychiatric disorders. In this report, we describe, for the first time, application of online tACS in a schizophrenia patient with working memory deficits. This case report supports the feasibility and potential utility of online tACS in schizophrenia, which needs further systematic research.

Abstract
UNLABELLED This systematic review assesses the quality and outcomes of published articles concerning bone graft surgery for scaphoid fracture non-union. Searches of the CENTRAL, MEDLINE, EMBASE, CINAHL and AMED databases captured 2710 articles. Each article was screened and 144 met our inclusion criteria. Data regarding source, study design, population, intervention, comparator and outcomes were extracted. There were 5464 scaphoid non-union outcomes within the 144 studies. Mean reported union rates for vascularized and non-vascularized bone graft were 84% and 80%, respectively. Avascular necrosis was diagnosed in several ways and, when present, the vascularized bone graft union rate was 74% compared with 62% with non-vascularized bone graft. Reported union rates vary considerably. These differences may be due to patient factors, fracture factors, treatment factors or study design failures or bias. We recommend that future researchers take into account the deficiencies of previous studies and use the suggested minimum data set in future studies. LEVEL OF EVIDENCE II.

Abstract
Aureofungin is a heptaene type of antifungal antibiotic used for controlling plant fungal infections and diseases, during pre and post harvesting period of various crops. Acute and subacute oral toxicity of aureofungin in rats was studied along with haematological, urine analysis and other biochemical parameters related to liver and kidney organ functions. The results of these studies indicate mild toxic symptoms at higher doses which were reversible following its withdrawal.

Abstract
The widely used agricultural antifungal agent aureofungin (ARF) was subjected to genotoxicity assessment using the Ames Salmonella assay as well as the in vivo micronucleus test and dominant lethal test in Swiss mice. In the Ames Salmonella spot test, ARF slightly elevated the number of histidine revertants after metabolic activation over a wide dose range (1-1000 micrograms/plate) in TA102 but not in TA97a, TA98 or TA100. In the preincubation plate incorporation assay with TA102, ARF increased the number of revertants in a dose-dependent manner only after metabolic activation. ARF failed to significantly elevate the frequency of micronucleated polychromatic erythrocytes (PE) in the bone marrow of Swiss mice. It elevated the frequency of dominant lethal mutations in the 7th and 8th weeks at 30 mg/kg body weight, a concentration much higher than the actual concentration used in the field. We conclude that ARF is non-mutagenic in somatic cells in vivo at doses used in the present study, probably mutagenic in stem-cell spermatogonia and may be classified as an equivocal promutagen, possibly acting as a cross-linker.

Abstract
Human alpha 2-macroglobulin and pregnancy zone protein are related with regard to primary structure, physicochemical properties, and quarternary structure. Both proteins undergo conformational changes when they form complexes with proteinases or react with primary amines. The surface properties of the native, chymotrypsin-treated and methylamine-treated forms of alpha 2-macroglobulin and pregnancy zone protein were studied by partitioning in aqueous two-phase systems composed of 7.5% dextran T70 and 5% poly(ethylene glycol) 8000. All proteins and their derivatives had a high potential for hydrophobic interaction as analyzed in terms of affinity for poly(ethylene glycol) esters of fatty acids included in the phase systems. Treatment of alpha 2-macroglobulin with methylamine or chymotrypsin increased the surface hydrophobicity significantly compared to that of the native protein. No difference in hydrophobic interaction was found for native and methylamine-treated pregnancy zone protein, but the chymotrypsin-treated protein showed a marked increase in binding to the hydrophobic ligand. The changes in surface hydrophobicity parallel changes in receptor binding properties of the derivatized forms of alpha 2-macroglobulin and could be a signal for binding to cell-surface receptors, followed by internalization.

Abstract
A mathematical model for the calculation of free and protein bound concentrations of testosterone and estradiol in plasma is presented. The method is based on the knowledge of the total concentrations of all steroids competing for the same binding site on testosterone-estradiol-binding globulin (TeBG), the concentration of albumin, the binding capacity of TeBG, and the association constants of the steroids to the two binding proteins. For the calculations we have determined the total concentrations of testosterone and estradiol. TeBG binding capacity, albumin concentration and the association constants for the binding of testosterone, estradiol and 5 alpha-dihydrotestosterone (DHT) to TeBG and albumin at 37 degrees C. Physiological concentrations of some androgen metabolites reported in the literature were also included in the calculations, namely: DHT, 5-androstene-3 beta, 17 beta-diol (Ae) and 5 alpha-androstane-3 alpha, 17 beta-diol (Aa). The binding constants for Ae and Aa to TeBG and albumin were also from the literature. Mean values of testosterone were calculated for 11 normal men and expressed as percentages of total: 2.0% was unbound, 53--55% bound to albumin and 43--45% bound to TeBG. For 16 normal women of a fertile age the corresponding values were 1.5%, 36--37% and 62%. For estradiol they were 2.4% 68--70% and 28--30% in the men and 2.0%, 52% and 45--46% in the women. Variations in the concentrations of DHT. Ae and Aa did not influence the free concentrations of testosterone and estradiol to any significant extent. It was furthermore concluded that the androgen metabolites could be omitted from the calculations without affecting the calculated concentrations.

Abstract
Needle aspiration of nodal and extranodal metastases of malignant melanoma was evaluated in 74 patients. All patients had the initial diagnosis of malignant melanoma established on surgical biopsy and histologic sections. A 20-cc glass syringe and an 18-gauge needle were used, and the material obtained was stained by the Wright-Giemsa technique. Adequate material was obtained, and a cytologic diagnosis of malignant melanoma was made in 67 patients (90.5%). In seven patients (9.5%) the specimens contained nondiagnostic material. The diversity of cell types, cytoplasm staining affinity and pigmentation is described. Despite the high variability of the cytologic features encountered, malignant melanoma usually can be diagnosed on cytologic smears. Difficulties in recognizing the nonpigmented varieties are emphasized. The procedure was well tolerated, and no complications were seen.

Abstract
Many biological macromolecules are known to interact either with themselves, with other macromolecules or with small compounds. A simple equilibrium method for detecting and quantifying these interactions is to study the mutual influence of the molecules on their respective counter-current distribution in liquid-liquid biphasic systems. The theoretical counter-current distribution patterns for the components in an interacting system, A + B in equilibrium AB, have been calculated for two models in order to establish the boundary conditions and to optimize the experimental procedure. The patterns have been calculated for a range of association constants, partition coefficients and initial concentrations of the two reactants.
