Coral reefs in the northeastern Saudi Arabian Red Sea are resilient to mass coral mortality events.

We conducted an integrated survey combining visual census and baited remote underwater video survey on the coral reefs in the northeastern Red Sea and examined their health by comparing the baseline information from two decades ago. The mean coverage of the corals of all stations was 36 %, including 32 % stony corals and 4.0 % soft corals, significantly higher and lower to previous baseline.

Impact of core polarity on smectic B-induced hydrogen bond liquid crystals.

The novel series of hydrogen bond liquid crystals were synthesized from the 2-methylglutaric acid (MGA) and 4-alkyloxybenzoic acid (nOBA) compounds. The induced smectic B phase with different texture (spine texture, needle texture, mosaic texture, natural mosaic texture and marble texture) were identified by polarizing optical microscope. Due to breaking of in-plane rotational symmetry within molecular layers, smectic B phase is tempted by suppressing other usual mesophases.

Pharmacogenomics in diabetes: outcomes of thiamine therapy in TRMA syndrome.

Aims/hypothesis: Diabetes is one of the cardinal features of thiamine-responsive megaloblastic anaemia (TRMA) syndrome. Current knowledge of this rare monogenic diabetes subtype is limited. We investigated the genotype, phenotype and response to thiamine (vitamin B) in a cohort of individuals with TRMA-related diabetes.

A 6-year-old boy with Wilson disease-A diagnostic dilemma.

A 6-year-old boy presented with 2 months history of progressive abdominal distension and jaundice. He was deeply icteric with ascites, hepatosplenomegaly, hyperbilirubinemia, raised transaminases, and coagulopathy. Viral markers and slit lamp examination for Kayser-Fleischer ring were negative.
