Physiological and molecular insights into the allelopathic effects on agroecosystems under changing environmental conditions.

Allelopathy is a natural phenomenon of competing and interfering with other plants or microbial growth by synthesizing and releasing the bioactive compounds of plant or microbial origin known as allelochemicals. This is a sub-discipline of chemical ecology concerned with the effects of bioactive compounds produced by plants or microorganisms on the growth, development and distribution of other plants and microorganisms in natural communities or agricultural systems. Allelochemicals have a direct or indirect harmful effect on one plant by others, especially on the development, survivability, growth, and reproduction of species through the production of chemical inhibitors released into the environment.

Eccrine Porocarcinoma of Dorsum of Nose: A Rare Case Report.

Eccrine porocarcinoma (EPC) is an uncommon malignant tumor derived from the eccrine sweat glands. Because of its various pathological features, it is often confused with other malignant cutaneous tumors. We present a case of 78-year- old female having ulcerative lesion over external nasal pyramid.

Phytoplankton diversity in relation to physicochemical attributes and water quality of Mandakini River, Garhwal Himalaya.

Phytoplankton are important biological indicators of water quality. This current study assessed the physicochemical parameters and phytoplankton diversity of Mandakini River, an important tributary of the River Ganga. Water and phytoplankton samples were collected from three sampling sites located at three different altitudes for a period of twelve months (July 2018-June 2019).

Prevalence of rheumatic and congenital heart disease in school children of Andhra Pradesh, South India.

Objective: To determine the prevalence of rheumatic heart disease (RHD) and congenital heart disease (CHD) using clinical and echocardiographic criteria in rural and urban school children in Andhra Pradesh, South India.

Materials And Methods: A total of 4213 school children between 5 and 16 years of age were screened. 1177 were from rural schools and 3036 from urban schools.

Doehle-Heller aortitis: speed of decision is what saves life.

A 48-year-old woman presented with severe acute heart failure of 7 days duration. Because of her rapidly worsening clinical condition, anatomical diagnosis of aortopulmonary fistula was made by urgent cardiac catheterization, and she successfully underwent immediate surgical closure. Retrospectively, the diagnosis of syphilitic aortitis complicated with aortopulmonary fistula was made by clinical profile, serology, and histopathology.

Device closure of post-myocardial infarction ventricular septal defect three weeks after coronary angioplasty.

Percutaneus device closure appears to be safe and effective in patients treated for a residual shunt after initial surgical closure, as well as after two to three weeks of index myocardial infarction. The index case presented with a ventricular septal defect on second of acute myocardial infarction thrombolysed with streptokinase. The general condition of the patient was fairly stable.

A tetrad of bicuspid aortic valve association: A single-stage repair.

We report a 27 years old male who presented with a combination of both congenital and acquired cardiac defects. This syndrome complex includes congenital bicuspid aortic valve, Seller's grade II aortic regurgitation, juxta- subclavian coarctation, stenosis of ostium of left subclavian artery and ruptured sinus of Valsalva aneurysm without any evidence of infective endocarditis. This type of constellation is extremely rare.
