We report a familial cluster of 2019 novel coronavirus disease (COVID-19) to assess its potential transmission during the incubation period. The first patient in this familial cluster was identified during the presymptomatic period, as a close contact of a confirmed patient. Five family members had close contact with this first patient during his incubation period, with four of them confirmed positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in the subsequent sampling tests.

Abortusequi ( Abortusequi) is the primary cause of abortions in equine animals, and can cause serious foodborne illness. Thus, effective biocontrol strategies are needed to decontaminate and control the emergence of foodborne diseases. In recent years, phages have been used as a new strategy for modulating foodborne pathogens and food safety.

In the contemporary era of drug discovery, herbal treatments have demonstrated an unparalleled ability to produce anticancer drugs. An important part of the therapy of cancer is the use of plants and their by-products via analogues, which alter the tumor microenvironment and several signaling pathways. The objective of the current investigation was to conclude the rate at which the herbal medications quercetin (QT) and sulforaphane (SFN) repressed the growth of breast carcinoma cells in MDA-MB-231 by preventing the ERK/MAPK signaling systems.

This paper presents the preparation of the parental experimental alloy, featuring a standard composition of TiYZrFeNiMn, via the vacuum induction melting technique. Subsequently, the TiYZrFeNiMn alloy, with an addition of 2 wt% Ni, underwent mechanical ball milling to yield a TiFe-based composite for experimental purposes. The results of the experimental tests indicate that the composite alloy's phase composition comprises the TiFe primary phase, with a minor quantity of ZrMn phase segregated on the surface of the primary TiFe phase, as well as Ni phase.
