The objective of this study was to examine the efficacy of the concurrent utilization of estradiol valerate and kuntai capsule (a Chinese herbal preparation) in addressing premature ovarian failure (POF) and its ramifications for ovarian hemodynamics and sex hormone levels. A retrospective study of 104 patients with POF was conducted, dividing them into control (n=50) and observation groups (n=54). The control group received estradiol valerate, while the observation group received estradiol valerate and KunTai capsules over 12 weeks. Clinical effectiveness, ovarian pulsatility index (PI), resistance index (RI), hormone levels, ovarian function, and adverse reactions were analyzed. The observation group showed significantly improved PI, RI, LH, FSH, E2 levels, and ovarian function in relative to the control group (P<0.05). We conclude that the concurrent use of estradiol valerate and KunTai capsules improves ovarian hemodynamics and hormone levels, offering significant clinical benefits.

Phagocytic clearance of apoptotic cancer cells (efferocytosis) by tumor-associated macrophages (TAMs) contributes in a substantial manner to the establishment of an immunosuppressive tumor microenvironment. This puts in context our observation that the female steroid hormone 17β-estradiol (E2) facilitates tumor immune resistance through cancer cell extrinsic Estrogen Receptor (ERalpha;) signaling in TAMs. Notable was the finding that E2 induces the expression of CX3CR1 in TAMs to enable efferocytosis of apoptotic cancer cells which results in the suppression of type I interferon (IFN) signaling.

To address this gap, we chart longitudinal changes in brain structure during pregnancy and explore potential mechanisms driving these changes.

Background: Reduced Bone Mineral Density (BMD) has been linked to Human Immunodeficiency Virus (HIV) infection and treatment. There is a lack of information regarding the osteoporosis status of middle-aged patients with HIV in Iran, despite the fact that Antiretroviral Therapy (ART) is widely accessible.
Objective: The purpose of this cross-sectional study was to assess the BMD status and low BMD risk factors in patients with HIV under ART living in Iran.

The injectable contraceptive, depot medroxyprogesterone acetate (DMPA), is associated with compromised cervical mucosal barriers. High-resolution spatial transcriptomics is applied here to reveal the spatial localization of these altered molecular markers. Ectocervical tissue samples from Kenyan sex workers using DMPA, or non-hormonal contraceptives, underwent spatial transcriptomics and gene set enrichment analyses.

Steroid hormones, especially progesterone (P), estradiol (E), and testosterone (T), are key bioactive regulators in various female physiological processes, including growth and development, ovulation, and the reproductive cycle, as well as metabolism and mental health. As lipophilic molecules produced in sex glands, these steroid female hormones can be transported through blood vessels into various body fluids such as saliva, sweat, and urine. However, the ultralow concentration of steroid hormones down to picomolar (pM) level necessitates great demands for ultrasensitive but low-cost analytic tools to implement accurate, point-of-care or even continuous monitoring in a user-friendly fashion.
