[The effect of exposure to prenatal life events and social support levels on low birth weight in offspring: a prospective cohort study].

To analyze the effects of exposure to life events and social support levels during different stages of pregnancy on low birth weight in offspring. From 2021 to 2023, pregnant women in early pregnancy who were registered with health cards in Linping District, Hangzhou City, were recruited and followed up. The Life Events Scale for Pregnant Women (LESPW) and Social Support Rating Scale (SSRS) were used to evaluate the exposure to life events and social support levels of pregnant women in early, middle and late pregnancy, respectively.

Association between influenza vaccination and prognosis in patients with ischemic heart disease: a systematic review and meta-analysis.

Background: There is substantial epidemiological evidence demonstrating that influenza contributes to cardiovascular events in patients who already have cardiovascular diseases. However, it is unclear the extent to which influenza vaccination influences the prognosis of patients with ischemic heart disease (IHD).

Methods: We conducted a search for eligible randomized controlled trials (RCTs) in PubMed, Cochrane, and Embase on March 11, 2024, to investigate the effect of the influenza vaccine on the prognosis of patients with IHD.

Effectiveness of the primary Bacillus Calmette-Guérin vaccine against the risk of Mycobacterium tuberculosis infection and tuberculosis disease: a meta-analysis of individual participant data.

Background: Tuberculosis vaccine trials using disease as the primary endpoint are large, time consuming, and expensive. An earlier immunological measure of the protection against disease would accelerate tuberculosis vaccine development. We aimed to assess whether the effectiveness of the Bacillus Calmette-Guérin (BCG) vaccine for prevention of Mycobacterium tuberculosis infection was consistent with that for prevention of tuberculosis disease.

Antimicrobial activity and immunomodulation of four novel cathelicidin genes isolated from the tiger frog Hoplobatrachus rugulosus.

Cathelicidin is a family of antimicrobial peptides in vertebrates that plays an important role in resistance and immunization against pathogenic microorganisms. In the present study, the full-length cDNA sequences of four novel cathelicidins (cathelicidin-1 to cathelicidin-4) in the tiger frog Hoplobatrachus rugulosus, encoding 153, 188, 132, and 160 amino acids, respectively, were firstly cloned by rapid amplification of the cDNA ends (RACE) technique. Sequence comparison and phylogenetic tree analysis indicated that the structures of the four cathelicidins are highly diverse.

Jatrophane and ingenane diterpenoids with anti-inflammatory activity from Euphorbia esula.

A phytochemical investigation into the plants of Euphorbia esula L. has yielded 19 diterpenoids, comprising 17 jatrophane-type (1-7 and 9-18) and two ingenane-type (8 and 19). The structures of these compounds were elucidated by a combination of spectrum elucidations, quantum chemical calculations, and X-ray single crystal diffraction.
