The carotid sinus nerve (CSN) is well known as mediating baroref lexes. However, studies of its detailed histologicalanalysis are scant in the literature. Therefore, the current anatomical study sought to better elucidate the microanatomy of theCSN. Ten fresh frozen adult cadavers underwent dissection of the CSN. Then, it was harvested and submitted for histologicaland immunohistochemical staining. Specimens were all shown to be nerve fibers on histology and immunohistochemistry. We identified tyrosine hydroxylase positive fibers in all CSN specimens. These fibers were always found to be within theCSN and not on its surface i.e., epineurium. Based on our findings, the majority of fibers contained in the CSN are tyrosinepositive in nature. Further studies are necessary to understand the true function of this autonomic nerve fibers.
A Study on the Risk Recognition and PROTECTION of Semi-Permanent Makeup in Female Students

Purpose: Since ancient times, the culture of putting on wounds or paints on the body like a tattoo has been carried on until now. In modern times, the interest, popularity, and market potential of semi-permanent makeup are increasing because it gives confidence and convenience as if wearing makeup. However, continuous research on safety is necessary because the risk factors for semi-permanent makeup are perceived in various aspects such as design, safety of ingredients, belief, worry, pain, and sanitary environment. Method: The researcher used the questionnaire method to construct questionnaire items with reference to previous studies. The questionnaire was constructed using a 5-point Likert scale and checklist. The questionnaire consisted of questions about demographic variables, the status of semi-permanent makeup, and risk perception factors. The subjects of this study were set as middle and high school girls and female university students from all over the country. The results were derived using frequency analysis. Results: The risk perception factors of semi-permanent makeup were design, eyebrow color, skin trouble, pain, and product and tool safety. However, there was an opinion(48.6%) that semi-permanent makeup should be performed by a beautician who is good at designing rather than a medical person. 46.4% answered that semi-permanent makeup is a type of makeup. However, as to the reasons for thinking that semi-permanent makeup should be regulated by the medical law, the highest responses were because it is more hygienic and the risk of infection is lower if it is done in a hospital and the difference in trustworthiness was the highest, and anesthetic cream was ranked next. Conclusion: According to the results of the study on risk perception and protection for semi-permanent makeup, it is recommended that a beautician with design and technology perform the procedure, but in terms of hygiene, infection, trust, and use of anesthetic cream, it should be regulated by the Medical Act. It is presumed to think that Therefore, as in the case of other countries, beauticians are allowed to perform semi-permanent makeup, but thorough education and management on semi-permanent makeup procedures, hygiene management, and safe use of products and tools are required.

The efficiency of high-power converters, especially for high-voltage direct current (HVDC) power transmission, represents a crucial issue. For modular multilevel converters (MMCs), a simple way to improve the efficiency is to drop the switching frequency. Nevertheless, to insure a proper control of the converter, the choice of the modulation method is essential. From this observation, the study throws light on two multilevel modulation methods to estimate their impact on converter efficiency. An average difference of 0.13% on the total efficiency of the converter is obtained between the two methods, with the possibility of using IGCTs optimized for low frequency operation.

The study of canine vector-borne diseases in the Philippines started in the 1970s but only gained interest in the past decade. Characterization of such diseases in the Philippines remains incomplete, thus, it is necessary to obtain additional information on the prevalence and diversity of canine tick-borne diseases in the country. In this study, blood samples were obtained at two veterinary clinics in Metro Manila, Philippines from 114 dogs suspected of having canine tick-borne pathogens. Polymerase chain reaction (PCR) was performed on whole blood DNA extracts followed by sequencing, and the following pathogens were detected: Hepatozoon (H.) canis (5.26%), Babesia (B.) vogeli (5.26%), Ehrlichia (E.) canis (4.39%), and Anaplasma platys (3.51%). Additionally, a set of multiplex PCR primers were developed to detect H. canis, Babesia spp. (B. canis and B. vogeli), and E. canis in canine blood. Multiplex and conventional single-reaction PCR results for the 114 dog blood samples were similar, except for one H. canis sample. Multiplex PCR is, therefore, a useful tool in screening infected dogs in veterinary clinics. This study's results, together with those of previous studies in the country, show that canine vector-borne pathogens are an emerging veterinary concern in the Philippines.
