Fever glove hand-shake method safe blood collection from children's fingertips in COVID-19 fever clinic.

Background: During the coronavirus disease 2019 (COVID-19) epidemic, the fever clinic is an important link for screening and diagnosing whether a patient is infected with the novel coronavirus. Blood collection from children's fingertips is a commonly used detection method; however, in children, the blood collection process may cause discomfort and resistance. To address this problem, the use of heating gloves combined with hand swinging can be considered for fingertip blood collection in children.

Fecal microbiota transplantation improves metabolism and gut microbiome composition in db/db mice.

Fecal microbiota transplantation (FMT) has become an effective strategy to treat metabolic diseases, including type 2 diabetes mellitus (T2DM). We previously reported that the intestinal microbiome had significant difference between individuals with normal glucose tolerance and T2DM in Chinese Kazak ethnic group. In this study, we investigated the effects of transplanted fecal bacteria from Kazaks with normal glucose tolerance (KNGT) in db/db mice.

TC1 (C8orf4) is involved in ERK1/2 pathway-regulated G(1)- to S-phase transition.

Although previous studies have implicated a role for TC1 (C8orf4) in cancer cell proliferation, the molecular mechanism of its action is still largely unclear. In this study, we showed, for the first time, that the mRNA levels of TC1 were upregulated by mitogens (FBS/thrombin) and at least partially, through the ERK1/2 signaling pathway. Interestingly, the over-expression of TC1 promoted the G(1)- to S-phase transition of the cell cycle, which was delayed by the deficiency of ERK1/2 signaling in fibroblast cells.

Expression of Pkd2l2 in testis is implicated in spermatogenesis.

Pkd2l2 is a novel member of the polycystic kidney disease (PKD) gene family in mammals. Prominently expressed in testis, this gene is still poorly understood. In this study, reverse transcription polymerase chain reaction (RT-PCR) results showed a time-dependent expression pattern of Pkd2l2 in postnatal mouse testis.

Characterization of a novel Xenopus SH3 domain binding protein 5 like (xSH3BP5L) gene.

SH3 domain binding protein 5 like (xSH3BP5L) gene encodes a protein that is a new found member of SH3 domain binding protein family which has been implicated at multiple levels of biological functions. Here, we have characterized Xenopus SH3 domain binding protein 5 like (xSH3BP5L) gene in the development of Xenopus laevis. Transcripts of xSH3BP5L were detected at all stages of development and in numerous adult tissues.

[Sequencing the Rhesus boxes and determining the homozygosity of RHD gene in Han Chinese with RhD negative].

Objective: To analyze the sequences of Rhesus boxes of RhD gene, and explore the genetic mechanism of RhD negative phenotype in Chinese Han population. Meanwhile the PCR product of Rhesus boxes is analyzed for determining RHD gene homozygosity.

Methods: DNA of 74 RhD negative samples were firstly analyzed with multiplex PCR-sequence specific primer(SSP).
