Photocatalysis has emerged as a promising approach for generating solar chemical and organic transformations under the solar light spectrum, employing polymer photocatalysts. In this study, our aim is to achieve the regeneration of NADH and fixation of nitroarene compounds, which hold significant importance in various fields such as pharmaceuticals, biology, and chemistry. The development of an in-situ nature-inspired artificial photosynthetic pathway represents a challenging task, as it involves harnessing solar energy for efficient solar chemical production and organic transformation.

Tuberculosis is a chronic communicable disease caused by Mycobacterium tuberculosis (Mtb) and spreads from lungs to lymphatic system. The cell wall of mycobacterium plays a prominent role in maintaining the virulence and pathogenicity and also acts as prime target for drug discovery. Hence, this study has put into emphasis with target MmpLs (Mycobacterial membrane proteins Large) which are significant for the growth and survival of Mycobacterium tuberculosis.

Armed conflict within nations has had disastrous humanitarian consequences throughout much of the world. Here we undertake the first comprehensive examination of the potential impact of global climate change on armed conflict in sub-Saharan Africa. We find strong historical linkages between civil war and temperature in Africa, with warmer years leading to significant increases in the likelihood of war.

This work is focused on the development of controlled drug delivery systems using different wax/fat embedded indomethacin (IM). Discrete wax/fat embedded microspherules containing indomethacin were prepared by using cetostearyl alcohol, paraffin wax and stearic acid by employing emulsification-phase separation method. These matrices have been used as barrier coatings due to their hydrophobic nature.

A study has been carried out to assess the potential use of pectin in combination with two added hydrocolloids, i.e., hydroxy-propyl-methyl cellulose and hydroxyethyl cellulose in varied concentrations and coated with ethyl cellulose and cellulose acetate phthalate.

Schistosomiasis is one of the commonest parasitic diseases affecting mankind. Egyptian schistosomiasis (mansoni and haematobium) is capable of producing fibrosis and/or calcification, resulting in striking radiological features in target organs. Our two cases with biliary and pancreatic calcification provide a combination of features not documented previously.

In four out of six gallbladders with schistosomal infestation, calcified granulomas were dense enough to be seen on abdominal radiographs. In one patient, faint calcification seen on a specimen of the excised gallbladder was not visible on the abdominal radiograph. Calcification on abdominal radiographs, especially serpiginous, seen in the region of the neck of gallbladder, appears to be the clue to the diagnosis of gallbladder schistosomiasis in people from endemic areas.

Calcification of the ureters, bladder and seminal vesicles was detected in six patients studied on computed tomography (CT) for evaluation of genitourinary schistosomiasis and in four others examined for intestinal schistosomiasis. Other findings included pyelocaliectasis in ten kidneys, vesical carcinoma in one, seminal vesicle granuloma in one and non-visceral calcification in pelvic tissue in one patient.

We report a sibship of two brothers and one sister with the osteoporosis-pseudoglioma syndrome and congenital heart disease. They presented in infancy with visual impairment and psychomotor retardation. Major features included bilateral cataracts, generalised osteopenia, severe platyspondyly, borderline mental retardation, muscular hypotonia, joint laxity, and ventricular septal defect.

We present an Arab family with some features of Kniest disease. The proband was a six year old boy with rhizomelic short limbed dwarfism, 'dish-like' facies, cleft palate, deafness, and camptodactyly. Most radiological changes were compatible with Kniest disease.

In a 6-month period, 25 appendices with histological involvement by schistosomiasis were radiographed. Eleven showed varying degrees of radiographically detectable calcification having a spotty, linear, or amorphous pattern affecting either a short segment or the whole appendix. Four of these appendices had a mixed pattern and one also had nodular calcification in the mesoappendix.

Schistosomal periportal fibrosis produced a typical pattern on computed tomography in five patients. Low-density periportal tissue, present throughout the liver, enhanced strongly after the administration of contrast medium. While rounded in cross section, the thickened periportal tissue produced linear and branching patterns when imaged in longitudinal section.

The hepatic sonograms of 22 patients with the features of schistosomal periportal fibrosis (PPF) were reviewed retrospectively. Dense echogenic bands were seen when scanning along the long axis of the intrahepatic portal vein radicles. Rounded densities resulted from scanning across these bands as they radiated from the porta hepatis to the liver's edge.

Rectocolonic calcification was detected radiographically in 17 sites in 14 patients undergoing excretory urography for the assessment of urinary schistosomiasis. The right colon was involved in 11 sites, the rectum in four, and the left colon in two. The pattern of calcification varied according to the degree of bowel distension.
