Resumen
In the second step of the molybdenum cofactor (Moco) biosynthesis in Escherichia coli, the l-cysteine desulfurase IscS was identified as the primary sulfur donor for the formation of the thiocarboxylate on the small subunit (MoaD) of MPT synthase, which catalyzes the conversion of cyclic pyranopterin monophosphate to molybdopterin (MPT). Although in Moco biosynthesis in humans, the thiocarboxylation of the corresponding MoaD homolog involves two sulfurtransferases, an l-cysteine desulfurase, and a rhodanese-like protein, the rhodanese-like protein in E. coli remained enigmatic so far.

Resumen
ABSTRACT Cells of Bacillus subtilis triggered to sporulate under conditions of rapid growth undergo a marked decrease in chromosome copy number, which was partially relieved by a mutation in the sporulation-induced gene yneE. Cells engineered to express yneE during growth were impaired in viability and produced anucleate cells. We conclude that YneE is an inhibitor of DNA replication.

Resumen
ABSTRACT CcdA is known to be required for the synthesis ofc-type cytochromes in Bacillus subtilis, but the exact function of this membrane protein is not known. We show that CcdA also plays a role in spore synthesis. The expression of ccdA and the two downstream genesyneI and yneJ was analyzed. There is a promoter for each gene, but there is only one transcription terminator, located after the yneJ gene. The promoter for ccdA was found to be weak and was active mainly during the transition from exponential growth to stationary phase. The promoters foryneI and yneJ were both active in the expon

Resumen
Background: Globally, breast cancer is one of the most common cancer among females of age group 15-40 years. India is also one of the leading countries of breast cancer. It is found that incidence rate of breast cancer is higher in less developing countries in comparison to development country. In 2018, worldwide, nearly 2 million new breast cancer cases were diagnosed. Early diagnosis of breast cancer can increase the chance of early case detection and favourable outcomes, resulting in improved survival rates and quality of life of women and is therefore important public health strategy at al

Background of the study: Nausea and vomiting are among the most common and distressing symptoms that patients with cancer endure, both as a result of anti – neoplastic treatment and from the disease itself, and significantly affect patients selfcare, coping abilities, and quality of life. Effective management of these individual symptom's response must be there throughout the cancer treatment. Since the acupressure is an easily applicable method regardless of time and place, cost effective, self-controlled and noninvasive method, it can be used to treat chemotherapy induced nausea and vomiting

Resumen
Background of the Study: Stunting, wasting, and underweight are the important nutritional status indicators for children. “While stunting is caused by long-term insufficient nutrient intake and repeated infections, wasting is a result of acute food shortage and illness. Wasting, on the other hand, is a strong predictor of mortality and requires urgent response. Underweight combines information about linear growth obstruction and weight for length/height” [7].

Yunvjian (YNJ) is a traditional Chinese medicine formula adopted to prevent and treat diabetes. Our previous results from animal experiments showed that YNJ decreased blood glucose. This study aimed to examine the effect of high glucose and high lipid (HG/HL) conditions on the proliferation and apoptosis of INS-1 cells and the possible protective mechanism of YNJ-medicated serum on INS-1 cells exposed to HG/HL conditions.

Resumen
Nearly all bacteria require iron for growth as it is utilised in many major biological processes. Despite its indispensability, iron causes problems of toxicity, poor solubility and poor bioavailability. Highly efficient iron acquisition and storage systems are used to overcome these problems. Gram-negative bacteria take up iron and haem complexes via specific outer-membrane (OM) receptors. Translocation across the OM is dependent on the cytosolic membrane potential and the energy transducing TonB-ExbB-ExbD system. Iron-complexes thus delivered to the periplasm are in tum translocated across t

Resumen
The starting material for this project was the highly functionalized compound 3,3,4,4- tetraethoxybut-1-yne (TEB) and it can be prepared from ethyl vinyl ether by a 4-steps synthesis. The third and the fourth step in TEB synthesis were sensitive to reaction conditions, so it was developed a strategy to try to optimize the third step and obtain TEB with higher yields. An approach, which tries to optimize also the fourth step, will be developed in further works. Several γ-hydroxy-α,β-unsaturated acetylenic ketones can be prepared from 3,3,4,4- tetraethoxybut-1-yne.
