Article Synopsis
- Researchers identified the roles of Methoprene-tolerant (Met) and Krüppel-homolog 1 (Kr-h1) in reproductive processes of the insect Liposcelis entomophila, focusing on vitellogenesis and ovarian development.
- Treatment with juvenile hormone (JH III) increased the levels of key proteins involved in reproduction, while silencing Met and Kr-h1 reduced these proteins, affecting egg production and lowering fertility.
- Additionally, disrupting these genes caused higher mortality rates in the insect, suggesting that targeting JH signaling could be a viable pest control method.
Article Synopsis
- Two unusual cases of distal bronchiolar adenoma were analyzed, focusing on their clinicopathological features, immunohistochemical characteristics, and genetic mutation profiles.
- Case 1 involved a 63-year-old female with a mixed ground-glass nodule showing mild cell morphology without significant mutations, while Case 2, a 58-year-old female, presented with a solid nodule revealing a HER2 gene mutation.
- The conclusion raises questions about the nature of these lesions—whether they are benign adenomas, precursors to malignancy, or similar to atypical breast hyperplastic lesions—and suggests further research on the prognostic implications of the HER2 mutation.
Background: Large cell neuroendocrine carcinoma (LCNEC) of the endometrium is an uncommon and highly aggressive tumor that has not been comprehensively characterized. We report a case of pure endometrial LCNEC and review the current literature of similar cases to raise awareness of the histological features, treatment, and prognosis of this tumor.
Case Summary: We report the case of a 73-year-old woman who presented with irregular postmenopausal vaginal bleeding.
The role of cell mediated immunopathogenesis in thyroid-associated ophthalmopathy.
Int J Ophthalmol
July 2019
Currently, thyroid-associated ophthalmopathy (TAO) lacks effective treatment due to our lack of clarity in its immunopathogenesis. Orbital fibroblasts play a key role in altering inflammation and immune response in TAO, and are considered as the key target and effector cells in its pathogenesis. The orbit infiltrating CD34+ fibrocytes add on to the process by expressing high levels of autoantigens and inflammatory cytokines, while also differentiating into myofibroblasts or adipocytes.

Aims: This study sought to investigate the relation of mother-infant attachment to attachment, cognitive and behavioural development in young children.
Study Design: This study used a longitudinal study design.
Article Synopsis
- There is a lack of research on infant attachment development in China compared to other countries, prompting this study focused on Shanghai.
- The study involved 160 healthy mother-infant pairs and assessed various factors like maternal sensitivity, marital satisfaction, and infant temperament.
- Results showed that 68.2% of infants were securely attached, with maternal and familial influences playing significant roles in attachment patterns, highlighting cultural differences in attachment in Shanghai.
[Comparison of the exposure rates of risk factors and inducing factors of acute myocardial infarction between younger and aged adults].
Zhonghua Liu Xing Bing Xue Za Zhi
March 2007
Objective: To study the clinical characteristics of acute myocardial infarction (AMI) among younger adults and to explore the possible mechanisms of early myocardial infarction, combined with the newly discovered risk factors of coronary heart disease.
Methods: Data on comparative analysis to the exposure rates of the risk factors and inducing factors of non-CAD patients with two groups of AMI patients including younger adults group (< or =40 years old) and aged adults group (> or =50 years old). Coronary angiography was applied.
The present study examined the relationship between word concreteness and word frequency using event-related potential (ERP) measurements during a lexical decision task. Potential effects of concreteness in the processing of verbs were also examined. ERPs were recorded from 119 scalp electrodes in 23 right-handed participants.
