The salivary gland cells of dipteran larvae, particularly the various species of Drosophila, have been of unusual interest to studies in genetics as well as investigations in cell differentiation. The giant polytene chromosomes in the nuclei of these cells have favored extensive cytogenetic analyses, and more recently the phenomenon of regional puffing of the salivary gland chromosomes has been...

A male, aged about 40 years, employed as a ' line' chowkidar, was admitted into the hospital on the 7th September, 1936, with the following symptoms :? Frequency of micturition for one year, the quantity passed on each occasion being very small and pain and irritability of the glans penis. These symptoms had become much worse during the past four or five days. There was a slight muco-purulent d...

more illustrations have been added. The main changes in the text are in the descriptions of the ciliary muscle, the substantia propria of the cornea, the vitreous, the zonule of Zinn, the distribution of the lachrymal fluid, the muco-cutaneous junction at the lid margin, the precorneal film, the retinal capillaries and the central connections of the visual apparatus. This is a superb book from ...

Dr. Leopoldo Di Iorio: On the basis of this clinical presentation, four main hypotheses were considered and simultaneously investigated. First, a cardiogenic shock was considered (subjects with Down’s syndrome can often have multiple cardiac abnormalities, such as atrium-ventricular channel, ventricular or atrial defects, Fallot’s tetralogy), but echocardiography excluded significant alteration...

In 1995 a report in the New England Journal of Medicine on medication use and risk of Stevens-Johnson syndrome/ toxic epidermal necrolysis (SJS/TEN) identified carbamazepine as a drug with a higher excess risk than most other drugs known to be associated with this severe muco-cutaneous drug reaction. Since then, pharmacogenomics (the study of the role of inherited and acquired genetic variation...

morning of the 13th November I was hurriedly called in to see him. He had after much coughing and sneezing evacuated a worm-like creature from his nose, and this had been thrown on the floor, where it looked like a small mass of muco-purulent nasal secretion with a streak of blood along it. In due course however it uncoiled itself to a length of about one inch and began to move very slowly. At ...

ver (temperature 103*6?), and complaining of cough, dyspnoea, headache, and pain in his chest. States that his illness commenced with a distinct chill and subsequent pains all over his body and fever. On physical examination, I found the patient iu a very weakly condition ; he had a quick pulse, and a dry furred tongue. On percussion there was slight duluess over the base of his right lung and ...

The brooding bivalves, Nutricola tantilla and N. confusa overlap in their geographic distributions, habitats, and modes and timing of reproduction. Based on previous studies we infer that males of both species release spermatozoa into the water column; while females retain developing embryos in a brood chamber. Females release fully formed juveniles and there is no pelagic larval stage. We hypo...

Primary systemic amyloidosis is a rare disorder characterized by multisystemic homogenous hyaline amyloid material. We report a case of 68 years old male presented with generalized weakness, fatigue, anorexia and impaired taste sensation. Muco-cutaneous lesions like, macroglossia with bullous haemorrhagic lesions, peri-orbital purpura, and nail changes were present. He had no cardiomegaly, hepa...

Leishmaniasis is a zoonotic and vector-borne infectious disease that caused by the genus Leishmania belonging to trypanosomatid family. The protozoan parasite has digenetic life cycle involving mammalian host an insect vector. Leishmaniasisis worldwide public health problem falling under neglected tropical category, with over 90 endemic countries, approximately 1 million new cases 20,000 deaths...
