OBJECTIVE This study was carried out to observe the prevalence breast diseases of males in our setup. METHOD All cases of male breast disease diagnosed from 1991-97. RESULTS One hundred and fifty (150) cases of male breast diseases were diagnosed. Age of the patients ranged from 4 to 90 years, with mean age 38.75 years (median = 33 years). Gynecomastia was the most common pathological abnor...

There are 9 serotypes of neuraminidase (NA) from influenza A virus (N1 to N9), which are classified into two groups based on primary sequences (groups 1 and 2). The structural hallmark of the two groups is the presence or absence of an extra 150-cavity (formed by the 150-loop) in the active site. Thus far, structures of NAs from 6 out of the 9 serotypes have been solved. Here, we solved the N5 ...

Context. Recent study of SDSS J1257+3419 has revealed that this stellar system is either a faint and small dwarf galaxy or a faint and widely extended globular cluster. Aims. In this short note, the author suggests that this system is one of the smallest dwarf spheroidals (dSphs) in the Milky Way. Methods. We re-examine some observational quantities of this object and check whether it can be bo...

We report the detection of a faint old stellar system at (α, δ) = (194.29 • , 34.32 •) (SDSS J1257+3419), based on the spatial distribution of bright red-giant branch stars in the Sloan Digital Sky Survey Data Release 4. SDSS J1257+3419 has a half-light radius of 38 ± 12 pc and an absolute integrated V-magnitude of M V = −4.8 +1.4 −1.0 mag at a heliocentric distance of 150 ± 15 kpc. A compariso...

Science expands knowledge not only through understanding but also through communication. Words form ideas, and words are tools for thoughts. The world looked very different 150 years ago. Scientific communication had a completely different language than now, and we were more strictly dependent on the spoken and printed word. The dissemination of new ideas was much slower than today, leading to ...
