Dystocia, a challenging condition in obstetrics, can arise from various causes, including fetal monsters with structural abnormalities. This case report presents a unique case of dystocia due to a fetal monster known as Perosomus Elumbis in a beetal breed goat from Pakistan. The 4-years-old pregnant doe presented with prolonged straining and failure to deliver the fetus after 8 hours of labor. Upon examination, the cervix was dilated, and only the forelimbs of the fetus were visible in the birth canal. The subsequent delivery involved the application of manual traction by using a dystocia kit, and the removal of edematous fluid from the legs. The monster fetus exhibited absence of hair growth, along with the absence of thoracic vertebrae. Two other fetuses were present, with one found dead and the other alive. Posttreatment involved fluid therapy, antibiotics, and supportive care for the doe. This case report sheds light on the occurrence of Perosomus Elumbis fetal monsters and their impact on dystocia in goat breeding. Understanding the underlying causes and implementing appropriate management strategies are crucial for successful outcomes in similar cases.

식물의 흡수를 통한 공기오염물질 제거는 생육 상태에 따라 그 효과가 달라진다. 실내에서 토양수분의 공급은 식물의 생 육을 위한 기본적인 관리 사항이다. 따라서 본 연구는 토양수 분함량에 따른 생리적 반응이 가스상 공기오염물질인 톨루엔 저감에 미치는 영향을 구명하고, 최적의 생육과 공기 정화 효 과를 위한 적정 토양수분함량을 찾고자 수행하였다. 이를 위 해 스파티필름과 파키라를 사용하여 40일 동안의 평균 토양 수분함량을 25%, 20%, 15%, 10%로 처리한 후 양자수율, 광 합성률, 기공전도도, 증산량 등 생리적 지수와 엽면적당 톨루 엔 저감량을 측정하였다. 그 결과 스파티필름은 토양수분함량 을 20~25%로 관리할 때 생육이 양호하고 최적의 톨루엔 저 감 효과를 얻을 수 있을 것으로 판단되며, 10% 이하 건조에 대한 주의가 요구된다. 반면 파키라는 토양수분함량 20% 이 하 처리구에서 톨루엔 저감량이 증가하였으나 10% 처리구에 서 생장량이 저하될 가능성이 있으므로, 공기 정화와 생육을 위한 최적 토양수분함량은 15~20% 범위이며, 25% 이상으로 장기간 유지하는 것은 과습을 유발할 가능성이 있는 것으로 판단된다.

Background: Reproductive management practices play crucial roles to maximize the reproductive performance of cows, and thus contribute to farm profitability. We aimed to assess the reproductive management of cows currently practiced in the dairy farms in an urban farming system. Methods: A total of 62 dairy farms were randomly selected considering all size of farms such as small (1-5 cattle), medium (6-20 cattle) and large farms (> 20 cattle) from selected areas of Dhaka city in Bangladesh. The reproductive managementrelated parameters viz. estrus detection, breeding method, pregnancy diagnosis, dry cow and parturition management, vaccination and treatment of reproductive problems etc. were obtained in a pre-defined questionnaire during the farm visit. Results: The visual observation method was only used (100.0%; 62/62) for estrus detection irrespective of size of the farms; while farmers observed cows for estrus 4-5 times a day, but only for 20-60 seconds each time. Regardless of farm size, 89.0% (55/62) farms used artificial insemination (AI) for breeding the cows. Intriguingly, all farms (100.0%) routinely checked the cows for pregnancy at 35-40 days post-breeding using rectal palpation technique by registered veterinarian. However, only 6.5% (4/62) farms practiced dry cow management. Notably, all farms (100.0%) provided nutritional supplements (Vit D, Ca and P) during late gestation. However, proper hygiene and cleanliness during parturition was not practiced in 77.4% (48/62) farms; even though 96.7% (60/62) farms treated cows by registered veterinarian for parturition-related problems. Conclusions: While farmers used AI service for breeding and timely check their cows for pregnancy; however, they need to increase observation time (30 minutes/ observation, twice in a day: early morning and early night) for estrus detection, consider dry cow management and ensure hygienic parturition for maximizing production.

The genera Spilonota Stephens, 1834 and Lepteucosma Diakonoff, 1971 are belonging to the tribe Eucosmini, subfamily Olethreutinae. In Korea, there are five species of Spilonota recorded: S. albicana (Motschulsky, 1866), S. eremitana Moriuti, 1972, S. lechriaspis Meyrick, 1932, S. ocellana ([Denis & Schiffermüller], 1775), and S. semirufana (Christoph, 1882). Only one species of Lepteucosma is recorded: L. huebneriana (Kocak, 1980). Both genera are agricultural pests that infest host plants belonging to the family Rosaceae, specifically causing damage to genus Malus (apple trees) and genus Rubus (blackberry plants), respectively. In this study, we provide a checklist of Korean Spilonota and Lepteucosma, with information of host plants and distribution for each examined species.

The subtribe Olethreutae Diakonoff (1973) which is one of the large subtribe in the subfamily Olethreutinae in the Tortricidae. Diakonoff classified the Olethreutae into a total of 27 genera and three genus groups: Olethreutes, Hedya, and Apotomis. According to the check list of insects from Korea (KSAE & ESK, 2021), 62 species from 11 genera of Olethreutae have been recorded in Korea. This study, provided with redescriptions, distribution, host plants, along with illustrations of adults, male and female genitalia are given.

The subfamily Epipaschiinae belongs to the family Pyralidae in the superfamily Pyraloidea. Moths of the epipaschiine are mostly medium-sized, and around 705 species have been described worldwide, with most of them distributed in Tropical and Temperate Regions (Nuss et al., 2023). In this study, 24 species of 10 genera of the subfamily Epipaschiinae are identified. All of the species are accompanied by distributions, host plants, and collection site information. Illustrations of adults, male and female genitalia are provided.

The striped fruit fly, Zeugodacus scutellata., is ubiquitous in agricultural areas, making it a critical pest to monitor and manage. It is necessary to develop a technique for rearing Z. scutellata in the laboratory to achieve mass production for biological control. The pumpkin is an important host plant for Z. scutellata; females lay their eggs on the tops of pumpkin flower buds, and larvae consume the stamens from top to bottom before dropping to the ground. Several types of diets are considered in the present study, including liquid, solid, and semisolid diets. Methyl benzoate, propionic acid, sodium benzoate, and citric acid were tested for their ability to suppress microbial contamination and improve the shelf life of diets. Fresh pumpkin, pumpkin flower, and pumpkin powder were used as primary ingredient. Reared adults were tested for their egg laying and survival abilities based on different diets. Approximately 86% of adults emerged from liquid and semisolid diets. Solid diets reduce pupae production and adult emergence. The diets with a total viability of less than 75% were discarded, which is considered as a reasonable threshold to determine whether a diet is nutritionally sufficient to rear the flies. Based on the results of the present study, we have developed a diet for mass rearing in laboratories, which may assist in providing a scientific basis for the effective control of Z. scutellata.

Two new species, Stericta jaeshini Kim & Bae, sp. nov. and S. atroaurantiaca Kim & Bae, sp. nov. are described from Laos and Cambodia. About 50 species of the genus Stericta have been recorded from Southeast Asia, but it has not been recorded to occur in Laos and Cambodia previously. We record the presence of this genus in these two countries for the first time in this study. Illustrations of adults and genitalia of examined species are provided.

According to Diakonoff (1973) subtribe Olethreutae is classified into a total of 27 genera and three genera groups: Olethreutes, Hedya, Apotomis. Up to data, 62 species belonging to 11 genera of Olethreutae have been reported in Korea(KSAE & ESK, 2021). In this study, we provide a checklist of subtribe Olethreutae with illustrations of adult, and genitalia of example species of each genus group.

Eucosmini Meyrick, 1909 is one of the largest groups in subfamily Olethreutinae, with more than 1,650 species of 128 genera. In Korea, 96 species of 26 genera have been recorded by several authors (Park, 1981, Bae, 1992, et al.). In this study, we provide a brief overview and a checklist of Eucosmini, with illustrations of adults and genitalia for examined species.

The striped fruit fly (SFF), Zeugodacus scutellata, is an agricultural pest species with a strong and rapid reproductive ability that can cause significant harm. To control the population of these kind of pests, the sterile insect technique (SIT) is being used as one of the effective methods. SIT involves the introduction of sexually transmitted factors that reduce the reproductive capacity of males. This study shows that knocking down the testis-specific serine/threonine protein kinase 1 (Zs-Tssk1) gene alters male fertility and male-initiated types of communication. Since Zs-Tssk1 influences the physiology of the testes, spermatogenesis is also affected, which in turn alters the lifespan of Zs-Tssk1 knock down group in comparison with the control. Based on these results, Zs-Tssk1 may be crucial in reproductive function, and its down-regulation may be helpful in controlling SFF through SIT.

Insect eggshell and cuticle/exoskeleton play vital roles in protecting them from natural environmental stresses. However, these chitinous cuticular extracellular matrices must be degraded at least in part during embryo hatching and molting/ecdysis periods to accommodate continuous growth all the way to the adult stage. In this study, we investigated the functional importance of groups I and II chitinases, TcCHT5 and TcCHT10, in the turnover of chitinous cuticle during both embryonic and post-embryonic development in Tribolium castaneum. RNAi and TEM analyses revealed that TcCHT10 is required for digestion of chitin in the serosal cuticle for embryo hatching as well as in the old cuticle during post-embryonic molts including larval-pupal and pupal-adult metamorphosis. TcCHT10 appears to be able to substitute for TcCHT5 in all these vital physiological events except for the pupal-adult molting in which TcCHT5 is indispensable for complete digestion of chitin in the old pupal cuticle.

Many insects form mutualistic relationships with microbial symbionts, crucial for their physiological processes. The bean bug, Riptortus pedestris, establishes a unique gut symbiosis with the genus Caballeronia and consistently acquires these symbionts from surrounding soil with each generation. As a result, the bean bug unavoidably consumes a variety of environmental microbes, including potential pathogens. To address this, the bean bug has developed a specialized organ in its midgut that selectively filters out non-symbiotic microbes, thereby preventing contamination of its symbiotic organ. In this study, we identified a pathogenic strain from the genus Burkholderia that lethally affects the bean bug post-invasion of the symbiotic organ. This pathogen employs a strategy of mimicking the motility of native symbionts to infiltrate the symbiont sorting organ and displays a pronounced resistance against antimicrobial agents produced by the host. Upon establishing itself in the symbiotic organ, the pathogen breaches the midgut cells, leading to host mortality, and subsequently disperses into the external environment. Our findings unveil a cunning pathogenic tactic that exploits the mimicry of native symbionts within an insect's symbiotic framework.

A 12-year-old intact female Schnauzer was referred for the evaluation of poorly controlled diabetes mellitus: despite insulin therapy, blood glucose concentration was consistently high, indicating a decreased insulin sensitivity. Laboratory analyses revealed persistent hyperglycemia, glucosuria, and ketonuria. Diagnostic approaches were performed to identify concurrent disorders that can cause insulin resistance. The dog was found to have concurrent hyperadrenocorticism, hyperlipidemia, pancreatitis, and vaginal cytology indicating diestrus in the estrus cycle. Trilostane administration for hyperadrenocorticism improved the insulin response; however, the dog remained hyperglycemic. Eventually, the dog showed complete remission without insulin administration 1 week after the ovariohysterectomy. The dog remained in remission for approximately 4 months, but eventually relapsed and the condition was permanent. Diestrus in intact females and hyperadrenocorticism are known to be the two main causes of insulin resistance in dogs. After the management of these conditions, the dog achieved diabetes remission, which rarely achieves in dogs. In cases of insulin resistance, such as hormonal imbalances or inflammatory conditions, remission can be achieved by addressing the underlying cause. Hence, it is important to assess the presence of comorbidities associated with insulin resistance in dogs with poorly controlled diabetes mellitus and to treat each condition as soon as possible.

Background: Germ cells undergo towards male or female pathways to produce spermatozoa or oocyte respectively which is essential for sexual reproduction. Mesenchymal stem cells (MSCs) have the potential of trans-differentiation to the multiple cell lineages. Methods: Herein, rat MSCs were isolated from bone marrow and characterized by their morphological features, expression of MSC surface markers, and in vitro differentiation capability. Results: Thereafter, we induced these cells only by retinoic acid supplementation in MSC medium and, could able to show that bone marrow derived MSCs are capable to trans-differentiate into male germ cell-like cells in vitro. We characterized these cells by morphological changes, the expressions of germ cell specific markers by immunophenotyping and molecular biology tools. Further, we quantified these differentiated cells. Conclusions: This study suggests that only Retinoic acid in culture medium could induce bone marrow MSCs to differentiate germ cell-like cells in vitro . This basic method of germ cell generation might be helpful in the prospective applications of this technology.

Porous carbons are considered promising for CO2 capture due to their high-pressure capture performance, high chemical/ thermal stability, and low humidity sensitivity. But, their low-pressure capture performance, selectivity toward CO2 over N2, and adsorption kinetics need further improvement for practical applications. Herein, we report a novel dual-templating strategy based on molten salts (LiBr/KBr) and hydrogen-bonded triazine molecules (melamine–cyanuric acid complex, MCA) to prepare high-performance porous carbon adsorbents for low-pressure CO2. The comprehensive investigations of pore structure, microstructure, and chemical structure, as well as their correlation with CO2 capture performance, reveal that the dual template plays the role of porogen for multi-hierarchical porous structure based on supermicro-/micro-/meso-/ macro-pores and reactant for high N/O insertion into the carbon framework. Furthermore, they exert a synergistic but independent effect on the carbonization procedure of glucose, avoiding the counter-balance between porous structure and hetero-atom insertion. This enables the preferred formation of pyrrolic N/carboxylic acid functional groups and supermicropores of ~ 0.8 nm, while retaining the micro-/meso-/macro-pores (> 1 nm) more than 60% of the total pore volume. As a result, the dual-templated porous carbon adsorbent (MG-Br-600) simultaneously achieves a high CO2 capture capacity of 3.95 mmol g− 1 at 850 Torr and 0 °C, a CO2/ N2 (15:85) selectivity factor of 31 at 0 °C, and a high intra-particle diffusivity of 0.23 mmol g− 1 min− 0.5 without performance degradation over repeated use. With the molecular scale structure tunability and the large-scale production capability, the dual-templating strategy will offer versatile tools for designing high-performance carbon-based adsorbents for CO2 capture.
