The main outcome was willingness to donate one's body after death. Predictors included demographics, residence, education/occupation, morbidity, comfort discussing voluntary body donation, information sources, knowledge (\"where to donate,\" \"who can consent,\" \"importance of body donation\"), perceived family agreement, and advocacy. Multivariable logistic regression estimated adjusted odds ratios (aORs) of 309 respondents (mean age 35.3±10.5 years; 64.1% male), the most frequently cited barrier to willingness was the desire to fulfil religious rites after death (52.3%).

At 15-16 weeks, chondrocytes in the anterior portion of the SPH-immediately anterior to the pituitary fossa-became slender or irregularly shaped with increased extracellular matrix, forming a distinct low-density zone (<8 cells per 0.1 mm<sup>2</sup>) compared with adjacent SPH cartilage (>15 cells per 0.1 mm<sup>2</sup>). In late-term fetuses (≥29 weeks), this zone expanded vertically to reach both the superior and inferior perichondria and appeared less basophilic, often containing fibrous or mesh-like structures. Notably, two late-term fetuses (35 and 39 weeks) displayed an additional anterior ossification center immediately in front of this low-density zone, creating a bipolar ossification pattern analogous to that of the PSept in non-human primates. In these specimens, parallel collagen bundles oriented supero-inferiorly were also observed across the interface. Taken together, these findings identify a reproducible, sparsely populated, fiber-containing cartilage region at the human SPH-ETH junction, frequently associated with an anterior ossification center.

Recent research has explored vitamin D3, particularly its active form, calcitriol, as an adjunctive treatment due to its neuroprotective effects. However, the exact mechanisms by which calcitriol mitigates ischemia-induced brain injury remain unclear. This study investigated the therapeutic potential of calcitriol in ischemia/reperfusion (I/R) injury using a rat model. Male Wistar rats were subjected to 1 hour of ischemia followed by 72 hours of reperfusion to establish an I/R injury model. The rats then received calcitriol treatment for three days. Neurobehavioral deficits and cerebral infarct volume were evaluated 72 hours post-ischemia. Oxidative stress markers-including malondialdehyde (MDA), nitric oxide (NO), and total antioxidant capacity (TAC)-were quantified. Additionally, RT-PCR was performed to assess mRNA expression levels of SIRT1 and PGC1-α. The study demonstrated that calcitriol administration significantly reduced cerebral infarct volume and improved neurological outcomes following I/R injury. Treatment with calcitriol effectively decreased oxidative stress markers, as evidenced by reduced MDA and NO levels, while simultaneously enhancing TAC. Notably, calcitriol treatment substantially upregulated mRNA expression of SIRT1 in ischemic brain tissue. Our results demonstrate that calcitriol exhibits neuroprotective effects against I/R injury.
