Bayesian analysis of joint quantile regression for multi-response longitudinal data with application to primary biliary cirrhosis sequential cohort study.

This article proposes a Bayesian approach for jointly estimating marginal conditional quantiles of multi-response longitudinal data with multivariate mixed effects model. The multivariate asymmetric Laplace distribution is employed to construct the working likelihood of the considered model. Penalization priors on regression parameters are incorporated into the working likelihood to conduct Bayesian high-dimensional inference.

Rh-Catalyzed [4 + 1] Reaction of Cyclopropyl-Capped Dienes (but not Common Dienes) and Carbon Monoxide: Reaction Development and Mechanistic Study.

Transition-metal-catalyzed [4 + 1] reaction of dienes and carbon monoxide (CO) is the most straightforward and easily envisioned cyclization for the synthesis of five-membered carbocycles, which are ubiquitously found in natural products and functional molecules. Unfortunately, no test of this reaction was reported, and consequently, chemists do not know whether such kind of reaction works or not. Herein, we report that the [4 + 1] reaction of common dienes and CO cannot work, at least under the catalysis of [Rh(cod)Cl].

Oncofetal protein IGF2BPs in human cancer: functions, mechanisms and therapeutic potential.

N-methyladenosine (mA) is the most prevalent and well-characterized internal chemical modification in eukaryotic RNA, influencing gene expression and phenotypic changes by controlling RNA fate. Insulin-like growth factor-2 mRNA-binding proteins (IGF2BPs) preferentially function as mA effector proteins, promoting stability and translation of mA-modified RNAs. IGF2BPs, particularly IGF2BP1 and IGF2BP3, are widely recognized as oncofetal proteins predominantly expressed in cancer rather than normal tissues, playing a critical role in tumor initiation and progression.

Tailoring the whole-cell sensing spectrum with cyborgian redox machinery.

Whole-cell biosensors are an important class of analytical tools that offer the advantages of low cost, facile operation, and unique reproduction/regeneration ability. However, it has always been quite challenging to expand the sensing spectrum of the host. Here, a new approach to extend the cell sensing spectrum with biomineralized nanoparticles is developed.

Progress in the genetic studies of spermatogenesis abnormalities.

About 15% couples suffer from infertility, half of which are caused by male factors. Male infertility usually manifests as teratozoospermia, oligospermia and/or asthenospermia, of which the most severe form is azoospermia. In this review, we summarize the recent progress in the study of genetic factors involved in nonobstructive azoospermia and teratozoospermia, Recently, with the rapid development of high-throughput chips and sequencing technologies, many genetic factors of spermatogenesis have been discovered and analyzed.

[Advances in proteomic studies of post-translational modifications during spermatogenesis].

Spermatogenesis is composed of a series of complex biological events, which are regulated by complex factors. There is a phenomenon of delayed translation in spermatogenesis, so the changes of transcription and protein expression are not completely consistent. Thus post-translational modifications (PTMs) play a key role in spermatogenic biological events.
