Abstract
We have identified a non-steroidal selective androgen receptor modulator (SARM), termed LY305, that is bioavailable through a transdermal route of administration while highly cleared via hepatic metabolism to limit parent compound exposure in the liver. Selection of this compound and its transdermal formulation was based on the optimization of skin absorption properties using both in vitro and in vivo skin models that supported PBPK modeling for human PK predictions. This molecule is an agonist in perineal muscle while being a weak partial agonist in the androgenic tissues such as prostate. When LY305 was tested in animal models of skeletal atrophy it restored the skeletal muscle mass through accelerated repair. In a bone fracture model, LY305 remained osteoprotective in the regenerating tissue and void of deleterious effects. Finally, in a small cohort of healthy volunteers, we assessed the safety and tolerability of LY305 when administered transdermally. LY305 showed a dose-dependent increase in serum exposure and was well tolerated with minimal adverse effects. Notably, there were no statistically significant changes to hematocrit or HDL after 4-week treatment period. Collectively, LY305 represents a first of its kind de novo development of a non-steroidal transdermal SARM with unique properties which could find clinical utility in hypogonadal men.

Abstract
BACKGROUND Incidence of extra-pulmonary tuberculosis is on the rise. Tuberculosis of breast is rare and have multifaceted clinical presentation, often mimicking carcinoma and pyogenic breast abscess. AIM To study morphologic variations and diagnostic difficulties of breast tuberculosis on fine needle aspiration cytology (FNAC). METHODS FNAC smears of breast tuberculosis were studied by Leishman's Stain and categorized into four groups. Cytology smears were also studied for presence of Acid Fast Bacilli (AFB) by Ziehl Neelsen (ZN) stain. Histology of excised tissue was studied by Hematoxylin and Eosin stain (H& E). RESULTS Out of 11 cases, 10 were females and 1 was male. Group 1 (n = 2) showed epithelioid granulomas with necrosis. Group 2 (n = 2) showed epithelioid granulomas without necrosis. Group 3 (n = 3) showed necrosis with a few scattered epithelioid histiocytes. Group 4 (n = 4) showed necrosis with numerous neutrophilic inflammatory cells. In four cases, caseous necrosis could be identified on cytology smears. AFB were found in five cases on FNAC smears. Histology confirmed diagnosis of tuberculosis in all cases. CONCLUSION In developing countries like India, based on clinical history and other features, FNAC smears showing epithelioid granulomas with or without necrosis should be considered as breast tuberculosis as demonstration of AFB is not mandatory. Identification of caseous necrosis alone is diagnostic of breast tuberculosis in cytology smears.

Abstract
BiFeO3 (BFO) multiferroic oxide has a complex phase diagram that can be mapped by using appropriately substrate-induced strain in epitaxial films. By using Raman spectroscopy, we conclusively show that films of the so-called supertetragonal T-BFO phase, stabilized under compressive strain, display a reversible temperature-induced phase transition at about 100 °C, and thus close to room temperature.

Abstract
BACKGROUND It is well accepted that heavy physical exertion can trigger the onset of myocardial infarction, but the mechanism is uncertain. As platelet and endothelial function play an important role in thrombotic events, platelet and prostacyclin responses to maximal treadmill exercise were studied. METHODS/RESULTS The study subjects were 40 healthy men, mean (SEM) age 29 (5) years. Platelet aggregation was measured on a four channel aggregometer. Plasma 6-keto-prostaglandin F1alpha was analysed using an enzyme immunoassay technique. Upright posture and exercise produced an increase in platelet aggregability, as indicated by a fall in the threshold concentration of adrenaline (epinephrine) from 7.6 (1.5) microM at rest to 4.3 (1.0) microM after exercise (p = 0.002). The collagen lag time became significantly shorter with exercise (from 79.1 (3.1) seconds at rest to 71.9 (2.6) seconds after exercise, p = 0.003). Exercise was also associated with a 55% increase in plasma 6-keto-prostaglandin F1alpha (from 38.1 (75%CI 29.0 to 46.5) pg/ml at rest to 59.2 (47.3 to 66.8) pg/ml after exercise, p<0.001). CONCLUSIONS In healthy male subjects, upright posture and maximal exercise increased platelet aggregability but this increase was counteracted by an increase in prostacyclin production. In patients with endothelial dysfunction, a reduced prostacyclin response to exercise may promote a transient prothrombotic imbalance that may trigger cardiovascular disease onset.

Abstract
Localized pericardial effusion leading to cardiac tamponade is seen occasionally in patients after cardiac surgery. This condition may be difficult to diagnose clinically because of unusual presenting symptoms and absence of conventional signs of cardiac tamponade. A case of localized pericardial effusion with presenting symptoms of fever and increasing fatigue is described in this study. The definitive diagnosis was made using transesophageal echocardiography. Surgical drainage of localized effusion resulted in prompt hemodynamic and symptomatic improvement.

Abstract
Various beta-lactam compounds and structurally related moieties were examined as substrates of beta-lactamase from Bacillus cereus 5/B NCTC 9946. The enzyme was specific for penicillins and none of the cephalosporins were hydrolysed. Electronic environment of allylic carboxy group in dihydrothiazine ring restricts the acceptance of cephalosporins as substrates. The efficiency of hydrolysis of penicillins is dependent on dense resonating electronic environment of phenyl ring present in the side chain, flexibility of the side chain and the distance between the phenyl ring and carbonyl group in the side chain.

Abstract
A 50-year-old woman had cervical lymphadenopathy, swollen and waxy-looking gums, and a diamond-shaped, reticular erythematous eruption on her back of eight years' duration. Histologic examination of the gingival tissue and skin showed round-cell infiltration around the small blood vessels and in the upper part of the dermis, and an extensive eosinophilic amorphous deposit throughout the dermis that stained with Alcian blue. The clinical and histologic features, although not identical, resembled those reported by Lischka and Orthenberger (1972) and later by Steigleder et al (1974).
