Objectives: To identify determinants of the course of Type 2 diabetes in Indian adolescents.
Methods: Records of 37 adolescents (24 boys; 29 post pubertal and eight pubertal) with Type 2 diabetes (initial HbA1C 10.1 ± 1.
Hyperandrogenism is a common condition encountered by pediatric and adolescent physicians. Most girls with hyperandrogenism represent physiological pubertal variation; pathology may be present in a substantial minority. Systematic evaluation is essential to avoid unnecessary work-up in physiological causes while not missing pathological causes.
View Article and Find Full Text PDFA novel simulation model (without using human corneas) has been described for understanding the surgical concepts and developing tactile reflexes of Descemet membrane (DM) endothelium scroll manipulation and orientation in the anterior chamber, which are necessary for performing Descemet membrane endothelial keratoplasty (DMEK). Termed the "DMEK aquarium," this model helps facilitate the understanding of different maneuvers of the DM graft needed inside the fluid-filled anterior chamber, like unrolling or unfolding, flipping or inversion, and checking orientation and centration in the host cornea. A stepwise plan for surgeons starting to learn DMEK utilizing various available resources is also suggested.

Two patients presented with localized corneal edema with a Descemet membrane (DM) tear in the left eye. Tomography of the right eye revealed localized steepening with increased maximum keratometry and decreased central pachymetry.

-transcribed messenger RNA (mRNA) has recently shown increasing significance in the development of vaccines and therapeutics. Immunogenic double-stranded RNA (dsRNA) is an undesired byproduct formed during transcription (IVT), and it is challenging to reduce dsRNA byproduct from mRNA due to their similar sizes and intrinsic characteristics. Removal of dsRNA relies heavily on post-IVT chromatography purifications, such as reverse-phase high-pressure liquid chromatography, which increase manufacturing costs, reduce yield, and often decrease integrity, especially for long mRNA.

We also studied their awareness, knowledge, and attitude toward universal precautions and guidelines.
Methods: The telephonic survey enrolled practicing cataract surgeons, who were interviewed to record responses pertaining to their practice using an open-ended questionnaire.
Influenza A virus (IFV) replicates its genome in the nucleus of infected cells and uses the cellular protein transport system for genome trafficking from the nucleus to the plasma membrane. However, many details of the mechanism of this process, and its relationship to subsequent cytoplasmic virus trafficking, have not been elucidated. We examined the effect of nuclear transport inhibitors Leptomycin B (LB), 5,6 dichloro-1-β-d-ribofuranosyl-benzimidazole (DRB), the vesicular transport inhibitor Brefeldin A (BFA), the caspase inhibitor ZWEHD, and microtubule inhibitor Nocodazole (NOC) on virus replication and intracellular trafficking of viral nucleoprotein (NP) from the nucleus to the ER and Golgi.

Design And Methods: Blood samples from total 408 subjects (217 COPD patients and 191 controls) were used for genotyping and estimating biolevels of α(1)AT, TIMP-1 and inflammatory cytokines. Data was analyzed to determine the role of interaction of TIMP-1 and α(1)AT genes; and interplay between various genotypes and biolevels of α(1)AT, TIMP-1 and inflammatory cytokines in development of COPD.
A series of nine 3-arylamino-1-chloropropan-2-ols 2a-2i were synthesized and their anti-fungal activity against pathogenic strains of Aspergillus fumigatus, Aspergillus flavus, Aspergillus niger and Candida albicans, and antibacterial activity against four pathogenic bacterial strains of Salmonella typhi, Pseudomonas aeruginosa, Streptococcus pneumonae and Staphylococcus aureus were evaluated using different assay systems. 1-Chloro-3-(4'-chlorophenylamino)-propan-2-ol was found to be the most active anti-fungal compound against three pathogenic strains under study, i.e.

All synthesized compounds showed mild to moderate activity, except for 2-substituted-10-methyl-1,2,3,4-tetrahydropyrazino[1,2-a]indoles 6a-d. The most active 1-(4-chlorophenyl)-10-methyl-1,2,3,4-tetrahydropyrazino[1,2-a]indole 4c exhibited a MIC value of 5.

The antibacterial activity was tested against Staphylococcus aureus (MTCCB 737), Pseudomonas aeruginosa (MTCCB 741), Streptomyces epidermidis (MTCCB 1824) and Escherichia coli (MTCCB 1652), and antifungal activity against Aspergillus fumigatus, Aspergillus flavus and Aspergillus niger. All synthesized compounds showed significant activity against bacterial strains but were found to be less active against tested fungi.
