Summary: The study found that SARS-CoV-2 survives longer on human skin compared to influenza A virus, increasing the risk of contact transmission and accelerating the pandemic. Proper hand hygiene is crucial in preventing the spread of the virus. Ethanol can completely inactivate both viruses within 15 seconds on human skin.

Summary: This study evaluated the disinfection effectiveness of alcohol-based disinfectants against SARS-CoV-2 and influenza A virus on human skin. The results showed that ethanol and isopropanol effectively inactivated the viruses, while chlorhexidine gluconate and benzalkonium chloride performed poorly in vitro but demonstrated higher effectiveness on human skin. The study highlights the importance of proper hand hygiene practices in preventing the spread of viruses.

Summary: The recent increase in unidentified cadavers worldwide is a serious problem. Raman spectrometry is used as a simple and objective method for forensic age estimation based on protein folding intensity ratio R-PF. The results indicate a high correlation between age and R-PF, with a model including linear and squared terms being the most accurate for age estimation.

Summary: This study investigated the diagnostic ability of CT scans based on the severity of coronary artery calcification in sudden cardiac death (SCD) cases. The results revealed that severe coronary artery calcification may increase the probability of SCD.

Summary: The study found that the oral health condition of all autopsy cases was worse compared to the SDD subjects, with the 80-20 achievement rate significantly lower in autopsy cases. Additionally, the average number of missing teeth in autopsy cases was not significantly different based on smoking status, BMI, and the presence of psychiatric disorders.

Summary: Alpha-ketoadipic acid is a metabolic intermediate of lysine and tryptophan and is associated with alpha-ketoadipic aciduria. Alpha-ketoadipic aciduria is a rare genetic disease characterized by metabolic abnormalities of lysine and tryptophan. This case report presents the sudden death of a 2-year-old boy with alpha-ketoadipic aciduria, with autopsy findings of fatty liver and urinalysis confirming increased excretion of alpha-ketoadipic acid.

Summary: This article describes a studio arson attack in Japan where dentists obtained dental findings from 33 unidentified bodies immediately after the attack and autopsy. The researchers examined the challenges faced by dentists while collecting these dental findings. They found that there was a significant increase in the number of dental findings obtained after autopsy compared to before autopsy for most bodies.

Summary: This study aimed to estimate the blood carbamazepine (CBZ) concentration from teeth and found that tooth CBZ concentrations were highly correlated with serum CBZ concentrations in rats. The study also revealed that CBZ concentrations in teeth did not substantially change after death, with high CBZ distribution observed in the pulp cavity.

Summary: Human chorionic gonadotropin (HCG) is an important indicator in clinical medicine for determining pregnancy. This study aimed to determine whether urine spots on a car seat from a murder case 5 years ago were from a pregnant woman. The dried urine spot on the car seat was tested using an immunochromatography kit to detect HCG. It was found that HCG can be detected in urine for longer periods of time than the previously reported 6 months.

Summary: This is a report about an unusual method of death by hanging, where one end of the rope is tied around the neck and the other end is tied to an immovable object and hung down to compress the neck with weight. In this case, we have identified a rare instance where death was achieved through the frictional force between the upward and downward ropes without tying one end. The police concluded the case as a suicide.
