Objectives : The aim of this study was to conduct a scoping review focusing on acupuncture points information applied in experimental studies using electroacupuncture for stroke. Methods : First, we set the research question of this study to identify which acupuncture points were studied for various symptoms of post-stroke sequelae in clinical and animal experiments. For this purpose, among the records searched through EMBASE, experimental studies including acupuncture points used in electroacupuncture treatment for stroke were selected as inclusion criteria for this study. The acupoints information used in each experiment was extracted from the included studies according to the type of study design and symptoms of stroke sequelae, and quantitative analysis was performed. Results : A total of 973 studies using acupuncture treatment, of which 429 papers including electroacupuncture were analyzed. Most of the animal experiments were conducted on general conditions instead of specific symptoms of stroke, and in clinical studies, electroacupuncture studies were conducted on symptoms such as hemiplegia and spasticity, cognitive and mental problems, dysphagia, shoulder problems, and depression that occur after stroke. Acupuncture points such as GV20, ST36, LI11, and LI4 were mainly used regardless of stroke symptoms. Except for these acupuncture points, GV26, GV14, GV16, and GV24 were frequently used in animal experiments, and TE5, LI15, LI10, and LR3 were widely used in clinical studies. Conclusions : Although this study extracted and analyzed only the frequent acupuncture points in the electroacupuncture study for stroke. However, in the future, it is necessary to be able to secure the evidence for acupuncture treatment elements through comparative studies between different acupuncture points or other elements constituting electroacupuncture.

Environmental stressors like pathogens and toxins may depress the animal immune system through invasion of the gastrointestinal tract (GIT) tract, where they may impair performance and production, as well as lead to increased mortality rates. Therefore, protection of the GIT tract and improving animal health are top priorities in animal production. Being natural-sourced materials, phytochemicals are potential feed additives possessing multiple functions, including: anti-inflammatory, anti-fungal, anti-viral and antioxidative properties. This paper focuses on immunity-related physiological parameters regulated by phytochemicals, such as carvacrol, cinnamaldehyde, curcumin, and thymol; many studies have proven that these phytochemicals can improve animal performance and production. On the molecular level, the impact of inflammatory gene expression on underlying mechanisms was also examined, as were the effects of environmental stimuli and phytochemicals in initiating nuclear factor kappa B and mitogen-activated protein kinases signaling pathways and improving health conditions.

Crop-animal systems which form the backbone of agriculture in the tropics are discussed with reference to their characteristics, economic importance of animals, genesis and types of crop-animal systems, relevance and potential importance, and priorities for research and development. These production systems are found across all agroecological zones: rain-fed temperate and highland systems, semi-arid and arid tropics, and sub-humid and humid tropics: the last four are priority areas in Asia. The potential importance of these systems in Asia is reflected in their advantages, synergism and complimentarity, economic benefits and contribution to sustainability. Illustrative case studies are cited which are appropriate to the two broad types of mixed farming systems: systems combining animals and annual cropping, and systems combining animals with perennial cropping with reference to Indonesia, Philippines, Malaysia, Sri Lanka, China and Nigeria. Priorities for research and development should address more complete use of the animal genetic resources, intensive utilisation of the feed resources, development-oriented utilisation of research results, minimizing animal diseases, and implementation of appropriate institutional and policy issues.

Several novel animal models that represent the pathophysiological process of endolymphatic hydrops (ELH) of Meniere's disease (MD) have been developed. Animal models are important to identify and characterize the pathophysiology of ELH and to corroborate molecular and genetic findings in humans. This review of the current animal models will be useful in understanding the pathophysiology of and developing proper treatments for MD. Surgical animal models will be replaced by medication-induced animal models. Study models previously developed in guinea pigs will be developed in several smaller animals for ease of conducting molecular analysis. In this review, we provided updated resources including our previous studies regarding the current and desirable animal models for MD.

This study aimed to analyze the leading research materials and research trends related to livestock food in Asia in recent years and propose future research agendas to ultimately contribute to the development of related livestock species. On analyzing more than 200 relevant articles, a high frequency of studies on livestock species and products with large breeding scales and vast markets was observed. Asia possesses the largest pig population and most extensive pork market, followed by that of beef, chicken, and milk; moreover, blood and egg markets have also been studied. Regarding research keywords, "meat quality" and "probiotics" were the most common, followed by "antioxidants", which have been extensively studied in the past, and "cultured meat", which has recently gained traction. The future research agenda for meat products is expected to be dominated by alternative livestock products, such as cultured and plant-derived meats; improved meat product functionality and safety; the environmental impacts of livestock farming; and animal welfare research. The future research agenda for dairy products is anticipated to include animal welfare, dairy production, probiotic-based development of high-quality functional dairy products, the development of alternative dairy products, and the advancement of lactose-free or personalized dairy products. However, determining the extent to which the various research articles' findings have been applied in real-world industry proved challenging, and research related to animal food laws and policies and consumer surveys was lacking. In addition, studies on alternatives for sustainable livestock development could not be identified. Therefore, future research may augment industrial application, and multidisciplinary research related to animal food laws and policies as well as eco-friendly livestock production should be strengthened.

The first part of this study reviewed the characteristics of calcium hydroxide ($Ca(OH)_2$) and summarized the results of in vitro studies related to its antimicrobial effects. The second part of this review covers in vivo studies including human clinical studies and animal studies. The use of $Ca(OH)_2$ as an intracanal medicament represented better histological results in animal studies. However, human clinical studies showed limited antimicrobial effects that microorganisms were reduced but not eliminated through the treatment, and that some species had resistance to $Ca(OH)_2$. Most of clinical outcome studies supported that there is no improvement in healing of periapical lesions when $Ca(OH)_2$ was applied between appointments. Further studies are required for the antimicrobial effects of $Ca(OH)_2$, and search for the ideal material and technique to completely clean infected root canals should be continued.

This review focuses on the nutritional effects from birth until age at first calving on growth, mammary developmental changes, and first-lactation milk yield in heifer calves. The advancement in the genetic potential and the nutritional requirements of the animals has hastened the growth rate. Genetic selection for high milk yield has suggested higher growth capacity and hence increasing nutritional inputs are required. Rapid rearing by feeding high energy or high concentrate diets not only reduces the age of sexual maturity but also lowers the time period of attaining the age of first calving. However, high energy diets may cause undesirable fat deposition thereby affecting future milk yield potential. Discrepancies exist whether overfed or overweight heifers at puberty can influence the mammary development and future milk yield potential and performance. The data on post-pubertal nutritional management suggested that body weight at calving and post-pubertal growth rate is important in first lactation milk yield. There is a continuous research need for strategic feeding that accelerates growth of dairy heifers without reduction in subsequent production. Nutritional management from birth, across puberty and during pregnancy is critical for mammary growth and for producing a successful cow. This review will mostly highlight studies carried out on dairy breeds and possible available opportunities to manipulate nutritional status from birth until age at first calving.

Animal in dustry in Korea urgently needs the domestic introduction and the industrial a, pp.ication of embryo transfer technique. Namely, this technique can be utilized effectively, as means of the improvement of livestocks, as means of the increase of meat production, as means of substitute for the livestock import, and dissemination of new breed. However, as this technique avaliable in our country is remaining initial stage, we can not make use of the technique industrially unless we make much improvement as follows; induction of superovulation, non-surgical recovery of embryos, synchronization between the estrus such cycles of donor and recipient, non-surgical transfer of embryos, etc. Simultaneously, the basic studies such as harvesting oocytes from ovary, in vitro culture of oocytes, in vitro capacitation of spermatozoa, cloning by culture of blastomeres and transfer of nuclei, sexing embryo, etc. should not be neglected in order to make the technique of embryo transfer more simple and convenient. For the success of these studies, universities, national and public institutes, large scale cattle farms, and small scale cattle farms should cooperate each other. For instance, universities undertake basic researches, and the national and public institutes a, pp.y the results of the researches to animal industry along with cooperation by large scale cattle farms. By the help of the cooperative organizations, the technique relevant to our environment and farm condition may be able to be finalized, and to be a, pp.ied to samll scale cattle farm. Consequently, being served to stimulate animal productivity, this technique can be contributed to the development of livestock industry in Korea.
