MicroRNAs play a central role in responses to biotic stressors through their interactions with their target mRNAs. Tea plant ( Camellia sinensis L.), an important beverage crop, is vulnerable to tea geometrid and anthracnose disease that causes considerable crop loss and tea production worldwide. Sustainable production of tea in the current scenario to biotic factors is major challenges. To overcome the problem of biotic stresses, high-throughput sequencing (HTS) with bioinformatics analyses has been used as an effective approach for the identification of stress-responsive miRNAs and their regulatory functions in tea plant...

The plant cuticle is the major barrier that limits unrestricted water loss and hence plays a critical role in plant drought tolerance. Due to the presence of stomata on the leaf abaxial surface, it is technically challenging to measure abaxial cuticular transpiration. Most of the existing reports were only focused on leaf astomatous adaxial surface, and few data are available regarding abaxial cuticular transpiration. Developing a method that can measure cuticular transpiration from both leaf surfaces simultaneously will improve our understanding about leaf transpiration barrier organization...

INTRODUCTION: Psoriasis is a very common chronic inflammatory skin disease affecting up to 3% of the general population with 75% of the psoriasis subjects being affected by a mild form of disease. Hence, topical therapy is the most frequent employed treatment in psoriasis also because it can be easily combined with systemic therapy. In this context, calcipotriol/betamethasone dipropionate (Cal/BD) fixed-dose association represents the first-line treatment due to its efficacy and once-daily application...

BACKGROUND: Heat stress factors (Hsfs) play vital roles in signal transduction pathways operating in responses to environmental stresses. However, Hsf gene family has not been thoroughly explored in tea plant (Camellia sinensis L.). RESULTS: In this study, we identified 25 CsHsf genes in C. sinensis that were separated by phylogenetic analysis into three sub-families (i.e., A, B, and C). Gene structures, conserved domains and motifs analyses indicated that the CsHsf members in each class were relatively conserved...

Purkinje cells (PCs) are principal cerebellar neurons, and several classes of interneurons modulate their activity. Lugaro cells (LCs) are one such inhibitory interneuron with distinctive cytology and location, but still most enigmatic among cerebellar neurons. Here we serendipitously produced a novel transgenic mouse line, where a half of Yellow Cameleon (YC)(+) cells in the cerebellar cortex were judged to be LCs, and YC(+) LCs were estimated to constitute one-third of the total LC populations. Neurochemically, two-thirds of YC(+) LCs were dually GABAergic/glycinergic, with the rest being GABAergic...

Neurological disorders and their sequelae, as of the widespread and critical humans complications, affect the body's nervous systems, organ functions, and behaviors. According to WHO, neurological disorders are currently predicted to affect more than one billion people globally. It is well-established that complementary medicine is one of the high accepted interventions that could have been considered for the management of neurological ailments. The current review aimed to compile a frame from all the crucial data reporting the investigation on the conspicuous intervention of green tea (made of Camellia sinensis) and related lead compounds (especially l-theanine, epigallocatechin-3-gallate, epicatechin-3-gallate, epicatechin, and epigallocatechin) for their neurological activities, mechanisms of action, and clinical properties...

It was on 31st December 2019, that a cluster of pneumonia cases was reported to the World Health Organization (WHO) by China. The initial investigations revealed the cases to be due to a previously unknown "never before seen strain of coronavirus". Coronaviruses are a group of viruses, which are normally present among animals such as cows, bats, camels and cats. The disease was officially named COVID-19 by WHO on 11th February 2020. The International Committee on Taxonomy of Viruses named the virus as SARS-CoV-2 due to its resemblance to SARS coronavirus...

Tea, a popular aromatic infusion and food supplement, prepared from Camellia sinensis (L.) Kuntze leaves, is often subjected to adulteration with various undeclared inorganic and plant-derived materials. Cashew (Anacardium occidentale L.) nut husk is one of the most common plant tea adulterants. To date, there are limited DNA-based technologies for tea authentication and quantitative detection of adulterants. Herein, we used a universal plant DNA barcoding marker coupled with High Resolution Melting (Bar-HRM) analysis to authenticate tea products from cashew ground nut...

BACKGROUND: Different procedures are available to help clinicians evaluate symmetry and cosmetic results in an objective manner after conservative breast cancer surgery. However, there are no similar methods in esthetic breast surgery, where the subjective assessment of the surgeon or the patient is usually considered the gold standard. The aim of this study is to evaluate the application of four software programs in the context of esthetic breast surgery and contrast their results with those of the subjective evaluation by a series of healthcare professionals...
