Unconventional posttranslational modification in innate immunity.

Pattern recognition receptors (PRRs) play a crucial role in innate immunity, and a complex network tightly controls their signaling cascades to maintain immune homeostasis. Within the modification network, posttranslational modifications (PTMs) are at the core of signaling cascades. Conventional PTMs, which include phosphorylation and ubiquitination, have been extensively studied.

Multistate Reaction Coordinate Model for Charge and Energy Transfer Dynamics in the Condensed Phase.

Constructing multistate model Hamiltonians from all-atom electronic structure calculations and molecular dynamics simulations is crucial for understanding charge and energy transfer dynamics in complex condensed phases. The most popular two-level system model is the spin-boson Hamiltonian, where the nuclear degrees of freedom are represented as shifted normal modes. Recently, we proposed the general multistate nontrivial extension of the spin-boson model, i.

Heterologous expression of heat stress-responsive AtPLC9 confers heat tolerance in transgenic rice.

Background: As global warming becomes increasingly severe, it is urgent that we enhance the heat tolerance of crops. We previously reported that Arabidopsis thaliana PHOSPHOINOSITIDE-SPECIFIC PHOSPHOLIPASE C9 (AtPLC9) promotes heat tolerance.

Results: In this study, we ectopically expressed AtPLC9 in rice to examine its potential to improve heat tolerance in this important crop.

[Trigger effect of hMG and hCG in the treatment of unexplainable non-obstructive azoospermia].

Objective: To investigate whether the trigger effect of human menopausal gonadotropins (hMG) and human chorionic gonadotropins (hCG) attributes to the treatment of unexplainable non-obstructive azoospermia (NOA).

Methods: We retrospectively analyzed the clinical data about 282 cases of unexplainable NOA treated in the Maternity and Child Health Hospital of Guizhou Province from January 2010 to May 2017. All the patients underwent trigger treatment by intramuscular injection of hMG at 75 IU 3 times a week for 2 weeks, followed by hCG at 2 000 IU twice a week for another 2 weeks, and meanwhile took vitamin E, Levocarnitine and Tamoxifen as an adjunctive therapy.
