Monkeypox virus vaccine evolution and global preparedness for vaccination.

The recent emergence of monkeypox (MPX) has created a global threat. The number of infected and suspected cases of MPX is increasing in different parts of the world, especially in non-African countries. However, vaccines are available to fight against this disease.

Ruptured sinus of Valsalva aneurysm due to Infective Endocarditis managed by device closure - a case report.

Ruptured sinus of Valsalva aneurysm (RSOV) is an uncommon cause of high output heart failure. RSOV most commonly opens into the right ventricle followed by the right atrium and non-coronary cusp involvement is relatively uncommon. Infective endocarditis (IE) is a rare cause of RSOV.

COVID-19 vaccine: Challenges in developing countries and India's initiatives.

Utility of global longitudinal strain to detect significant coronary artery disease, its extent and severity in patients with stable ischemic heart disease.

Background: Early changes in cardiac function due to ischemia may be detected by global longitudinal peak systolic strain (GLS). Till date, no Indian data exist regarding role of GLS in stable ischemic heart disease (SIHD) and data showing correlation of GLS and SYNTAX score (SS) is meager in world literature. Our aim was to ascertain the role of GLS in SIHD.

Trans-catheter closure of a large aneurysm in coarctation of abdominal aorta.

•Here, we are presenting a very rare case of coarctation of abdominal aorta where a transcatheter closure by a vascular plug of the feeding collateral to a large aneurysm has been done. To the best of our knowledge, this mode of therapy has never been described in persons with coarctation of abdominal aorta.•Aneurysms in patients with an abdominal coarctation are not well recognized.

Effect of sulphydryl reagents on the heat stability of whey protein isolate.

The effects of sulphydryl (-SH) reagents on protein aggregation reactions in heated whey protein isolate (WPI) and pure α-lactalbumin (α-La) were investigated. In contrast to its previously reported effect with pure β-Lg, dihydrolipoic acid (DHLA) markedly reduced the heat stability of WPI, especially the α-La component, which aggregated much more readily in the presence of DHLA than in WPI alone. Whilst pure α-La is quite stable to heat, it is much less stable in the presence of DHLA.

Effects of emulsion droplet sizes on the crystallisation of milk fat.

The crystallisation properties of milk fat emulsions containing dairy-based ingredients as functions of emulsion droplet size, cooling rate, and emulsifier type were investigated using a differential scanning calorimeter (DSC). Anhydrous milk fat and its fractions (stearin and olein) were emulsified with whey protein concentrate, sodium caseinate, and Tween80 by homogenisation to produce emulsions in various size ranges (0.13-3.

Reduction of aggregation of β-lactoglobulin during heating by dihydrolipoic acid.

Prevention of the heat-induced aggregation of β-lactoglobulin (β-Lg) would improve the heat stability of whey proteins. The effects of lipoic acid (LA, or thioctic acid), in both its oxidised and reduced form (dihydrolipoic acid, DHLA), on heat-induced unfolding and aggregation of β-Lg were investigated. LA/DHLA was added to native β-Lg and the mixture was heated at 70, 75, 80 or 85 °C for up to 30 min at pH 6·8.

Left ventricular diastolic dysfunction in COPD may manifest myocardial ischemia.

Background: Left ventricular diastolic dysfunction (LVDD) is observed frequently in advanced COPD and it appears unrelated to the co-presence of its common risk factors as hypertension, diabetes, ischemic heart disease, etc. The patho-physiology of this association is yet unclear. We postulated that ischemia not apparent in the routine clinical evaluation could be the cause of such LVDD.
