Background and Objectives: The landmark for neurosurgical approaches to access brain lesion is the pterion. The aim of the present study is to classify and examine the prevalence of all types of pterion variations and perform morphometric measurements from previously defined anthropological landmarks. Materials and methods: One-hundred and twenty-four Thai dried skulls were investigated. Classification and morphometric measurement of the pterion was performed. Machine learning models were also used to interpret the morphometric findings with respect to sex and age estimation. Results: Spheno-parietal type was the most common type (62.1%), followed by epipteric (11.7%), fronto-temporal (5.2%) and stellate (1.2%). Complete synostosis of the pterion suture was present in 18.5% and was only present in males. While most morphometric measurements were similar between males and females, the distances from the pterion center to the mastoid process and to the external occipital protuberance were longer in males. Random forest algorithm could predict sex with 80.7% accuracy (root mean square error = 0.38) when the pterion morphometric data were provided. Correlational analysis indicated that the distances from the pterion center to the anterior aspect of the frontozygomatic suture and to the zygomatic angle were positively correlated with age, which may serve as basis for age estimation in the future. Conclusions: Further studies are needed to explore the use of machine learning in anatomical studies and morphometry-based sex and age estimation. Thorough understanding of the anatomy of the pterion is clinically useful when planning pterional craniotomy, particularly when the position of the pterion may change with age.

Thai Mucuna pruriens (L.) DC. var pruriens (T-MP) seed containing levodopa (L-DOPA) and antioxidant capacity has been shown to improve sexual behavior and male reproductive parameters in rats treated with ethanol (Eth). However, its protective effect on testicular apoptotic germ cells has never been reported. This study aimed to investigate the potential effects of T-MP seed extract on expressions of caspase, proliferating cell nuclear antigen (PCNA), and dopamine D2 receptor (D2R) proteins in Eth rats. Thirty-six male Wistar rats were divided into four groups (9 animals/group), including control, Eth, T-MP150+Eth, and T-MP300+Eth, respectively. Control rats received distilled water, and Eth rats received Eth (3g/kg BW; 40%v/v). The T-MP groups were treated with T-MP seed extract at a dose of 150 or 300 mg/kg before Eth administration for 56 consecutive days. The results showed that the seminiferous tubule diameter and epithelial height were significantly increased in both T-MP treated groups compared to the Eth group. Additionally, the caspase-9 and -3, and PCNA expressions were decreased, but D2R expression was markedly increased in T-MP groups. It was concluded that T-MP seed extract could protect testicular apoptosis induced by Eth via changes in caspase, PCNA, and D2R protein expressions.

Chronic stress (CS) is known to induce testicular oxidative stress and apoptosis. Fruit of Momordica charantia (FMC) has antioxidant capacity to protect tissue damage, but its effect on sexual activity and testicular damage caused by CS has never been documented. This study aimed to investigate the impact of FMC extract against testicular damage and sexual dysfunction in chronic unpredictable stress (CUS) rats. Rats were divided into four groups and pretreated with vehicle or FMC (40 and 80 mg/kg) before CUS induction for 56 days. Sexual behaviors, serum hormones, and sperm quality were analyzed. Testes were collected to determine daily sperm production (DSP), malondialdehyde (MDA) level, and expressions of cleaved apoptotic proteins. Testicular DNA fragmentation, as revealed by TUNEL and morphometric analysis, was observed. FMC improved sexual activity, increased testosterone levels, and sperm count with improvements in DSP, testicular morphometrics, and MDA levels. Moreover, TUNEL-positive cells and expression of caspase 3 in the testis were decreased in FMC rats. FMC has antioxidant potential and could protect against male sexual dysfunction and testicular damage caused by stress-related apoptosis. It is a potential extract to be developed as a supplement in preventing CS-male subfertility. However, future studies about the optimal dose and clinical trials are required.

Chronic stress (CS) contributes to male infertility, reduced testosterone levels, and impaired semen quality. CS models induced by glucocorticoids, such as dexamethasone (DEX), negatively affect sperm parameters and testicular health, notably by promoting testicular apoptosis. While individual plant extracts have been studied for their ability to mitigate stress-induced reproductive dysfunction, the preventive effect of the Tri Garn Pis (TGP) polyherbal extract in DEX-induced CS (DexCS) has not previously been investigated. This study evaluated the effects of TGP extract on testicular function, sexual behavior, and sperm quality in DexCS male mice. Seventy-two ICR mice were randomly divided into six groups: control, DexCS, TGP (50, 100, and 200) + DexCS, and TGP200. Mice received TGP (50, 100, 200 mg/kgBW) for 14 days before DEX co-treatment for 28 days. Behavioral and reproductive assessments included depression-like behavior tests, sexual behavior, sperm quality, testicular histopathology, steroidogenesis proteins (AR, CYP11A1, StAR), and apoptosis markers (Hsp70, caspase-3, caspase-9). TGP extract—which is rich in phenolics and flavonoids with antioxidant activity—improved depressive behavior, sexual performance, testicular histology, and low sperm quality. TGP also upregulated testicular StAR expression while reducing caspase-3 and caspase-9 levels. TGP prevents testicular apoptosis, sexual dysfunction, and poor sperm motility induced by DexCS.

At present, a novel herbal regimen targeting anti-insomnia, anti-anxiety, cognitive performance, and anti-depression effects is required due to the limitations of the current therapy. Based on the crucial role of oxidative stress in the pathophysiology of stress-related brain disorders, it was hypothesized that the functional ingredient derived from mulberry leaves and butterfly pea flowers, which exhibits potent antioxidant activity, should protect against the disorders just mentioned. Male Wistar rats (180–200 g) were orally administered at doses of 125, 250, and 500 mg/kg BW once daily, 45 min before exposure to a 6-h immobilization stress for 14 days. Behavioral assessments, including sleep, anxiety, spatial memory, and depression, were assessed every 7 days. At the end of the study, corticosterone levels, oxidative stress markers, neurotransmitters, IL-6, BDNF, and neuron density in the prefrontal cortex and hippocampus were measured. The functional ingredients demonstrated anti-insomnia, anxiolytic, memory-enhancing, and antidepressant properties. It also increased neuron density and BDNF and activity of SOD and CAT enzymes, whereas corticosterone, GABA-T, AChE, MAO, IL-6, and MDA levels were reduced. A potential regimen targeting showed the benefits of anti-insomnia, anxiolytic, memory-enhancing, and antidepressant properties. However, further studies regarding the precise underlying mechanism and a clinical trial are essentially required.
