This study investigates the impact of TH deficiency, induced by thiourea, a known inhibitor of thyroid peroxidase (TPO), on the development of domestic chicks. Thiourea was administered before thyroid gland formation, and its presence in treated embryos was confirmed through liquid chromatography-mass spectrometry. In silico docking revealed a strong interaction between thiourea and the CCP-like domain of TPO, which was corroborated by TPO activity assays showing reduced enzyme function. This reduction in enzyme activity led to lower embryonic TH levels and increased thyroid-stimulating hormone (TSH) secretion. Morphological analysis of newly hatched chicks revealed significant structural anomalies, particularly in lateral plate mesoderm-derived structures, including omphalocele, limb deformities, anophthalmia and craniofacial defects. Alcian blue and Alizarin red staining demonstrated reduced ossification in ribs and forelimbs, while histological analysis showed incomplete abdominal wall closure and abnormal vertebral column development. Haematological profiling of TH-deficient newly hatched chicks revealed significantly lower blood cell counts, highlighting TH's critical role in haematopoiesis. These findings emphasise the multifaceted role of TH in embryonic development, with potential implications for understanding congenital hypothyroidism and its developmental impacts, especially in regions with limited healthcare access.\u0000 </div>","PeriodicalId":49290,"journal":{"name":"Anatomia Histologia Embryologia","volume":"53 5","pages":""},"PeriodicalIF":0.8,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142234693","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has been observed that studies on skulls help to determine species and sex. In recent years, craniometric studies have been frequently used to determine morphometric features in animals. In our study, 150 skulls were studied, 50 from the second trimester (25 males and 25 females), 50 from the third trimester (25 males and 25 females), and 50 from the third and fourth week after birth (25 males and 25 females). The skulls were sectioned by computerised tomography and stored in DICOM format. From the images, nine different measurements and five index calculations were made. The similarities and differences between species were determined by ignoring sex differences. Correlation analyses were performed to compare measurement parameters between animal species. In addition, the results of statistical analyses between sexes were evaluated without species distinction. SL, CW and ICI parameters were highly statistically significant between measurements in the second trimester, third trimester and postnatal group (p < 0.01). In the third trimester, the EHC measurement parameter was found to be highly significant between males and female (p < 0.01). In Table 5, the CL parameter was positively correlated with CW, IHC, EHC, ILC, ELC, FMW and FMH. There are very few studies on foetal development.

The diameters of NFs were measured. The length, width, and distances of the NF to the proximal and cranial edges were measured. Foraminal indices were also calculated. It was determined that the average number of NF per scapula was 1.8. The location of the NFs was 52% on the medial aspect and 48% on the lateral aspect. On the medial aspect of the scapula, NFs were frequently found ventrally, on the neck region of the scapula. Laterally, 40 NFs were found in the ventral region of the infraspinatus fossa and only 12 in the ventral region of the supraspinatus fossa.

The unique anatomical structure of the kidney enables the camel to prevent water loss. The present study aimed to investigate the ultrastructure of the peroxisomes in the normal kidney of the adult dromedary camel. Tissue samples were taken from the cortex and outer medulla of the kidney of eight camels. The samples were then processed for histological and ultrastructural investigations. The epithelial cells of the proximal tubules displayed peroxisomes with varying sizes and shapes. The peroxisomes were observed in either dispersed or clustered arrangement. Each peroxisome exhibited a homogenous matrix enveloped by a single membrane. Several peroxisomes exhibited one or more dark marginal plates that were always strongly associated with the smooth endoplasmic reticulum. The intensity of the peroxisomal matrix differed significantly, either within the same cell or across different cells. The intensity was light or dark, with a few peroxisomes presenting a similar intensity to that of the mitochondria. Some peroxisomes contained nucleoids within their matrix. The peroxisomes in the first and second sections of proximal convoluted tubules were scattered and primarily located in the region between the microvilli and the underlying mitochondria. The peroxisomes in the third region were abundant and frequently aggregated in clusters throughout the cytoplasm. In the fourth region, the number of peroxisomes was low. The proximal straight tubule had a limited quantity of peroxisomes. In conclusion, peroxisomes in the proximal tubule in kidney of normal dromedary camel were similar in shape and size to other mammals; however, heterogeneity exists as a result of differences in species-specific peroxisomal proteins. Peroxisomes are suggested to be a major source of metabolic energy and act as hydrogen peroxide (H2O2) scavengers, resulting in the release of water and oxygen.","PeriodicalId":49290,"journal":{"name":"Anatomia Histologia Embryologia","volume":"53 5","pages":""},"PeriodicalIF":0.8,"publicationDate":"2024-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142001269","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ten-week-old male Wistar albino rats were divided into three groups: control (n = 6), damage (DG) (n = 6) and testicular stromal stem cell (TSSC) (n = 6) groups. Surgically induced damage was inflicted on the left testes of both the DG and TSSC groups, with no intervention on the right testes. In the TSSC group, damaged testes were treated with transplanted tSSCs, followed by orchiectomy after 15 days. Testes tissues were stained with haematoxylin–eosin (H&E), and recovery rates of functional structures were assessed by modified Johnsen scoring. The effects of tSSCs on testicular tissue were demonstrated by immunohistochemistry using BAX, BCL-2 and caspase 3. Serum testosterone levels were analysed using the enzyme-linked immunosorbent assay (ELISA) method. Surgical damage caused germ cell degeneration in some seminiferous tubules and a decrease in interstitial areas. With tSSC treatment, improvements in testicular architecture were identified through spermatogenesis in the seminiferous tubules and normal histological structures in the interstitial areas. Correspondingly, in the modified Johnsen score, the DG group showed a significant difference compared to the other groups (p = 0.001). High expressions of BAX, BCL-2 and caspase-3 in the DG group revealed prominent features of apoptosis. With the injection of tSSCs, these expressions significantly normalized according to H score analysis (all p = 0.004). Although serum testosterone levels in the tSSC group were higher compared to the control and DG groups, this difference was not statistically significant (p = 0.119). This study suggests transplanting tSSCs could accelerate tissue healing after testicular sperm extraction (TESE) surgery for azoospermia patients, potentially paving the way for a new and important clinical treatment.","PeriodicalId":49290,"journal":{"name":"Anatomia Histologia Embryologia","volume":"53 5","pages":""},"PeriodicalIF":0.8,"publicationDate":"2024-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141977134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One breeding objective is the ability to digest low-quality feed. Certain measurements of the gastrointestinal tract may be useful indicators of this ability. The present study compared the gastrointestinal tract of adult hens of two layer-type breeds (White Rock (WR), New Hampshire (NH)) and the meat-type ÖTZ (Ökologische Tierzucht gGmbH) Bresse Gauloise (BR), used for the production of dual-purpose organic chickens. Flocks had the same housing and feeding conditions. At slaughter at 19 months, the body weight and gastrointestinal organs of 134 hens (51 WR, 55 NH and 28 BR) were measured. The muscle thickness of the proventriculus and ventriculus and the length and width of the duodenum, jejunoileum, caeca and colorectum were measured and variances between the groups were analysed using a one-factor covariance analysis. Significant differences between the breeds were found in total intestine length and the lengths and/or widths of single gastrointestinal segments. For example NH showed the highest mean total intestinal length and BR showed the lowest mean (NH: 186.73 cm, WR 185.86 cm, BR 157.91 cm; p = 0.001). To our knowledge, this is the first study comparing the gastrointestinal tract size of adult female layer- and meat-type chicken breeds kept under the same feeding and housing conditions. Given the possible relationship between intestinal length parameters and chicken performance, measurement of the gastrointestinal tract may be a simple, quick and inexpensive additional method to help select layer-, meat-type and dual-purpose chickens suitable for organic production when a selection process using genetic markers is not possible.","PeriodicalId":49290,"journal":{"name":"Anatomia Histologia Embryologia","volume":"53 5","pages":""},"PeriodicalIF":0.8,"publicationDate":"2024-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ahe.13098","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141898854","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A promising technique to quantitatively measure subtle changes in expression patterns, including changes invisible to the human eye, is surface electromyography (sEMG).

We aimed to localize the nerve entry points (NEPs; where the nerve branch first pierced the muscle belly) and the direction of the terminal nerve endings to estimate MEP locations of the innervating nerves in five equine facial muscles involved in pain expression. Three cadaveric Dutch Warmblood horse heads were dissected to identify the NEPs in the musculi caninus, levator anguli oculi medialis, nasolabialis, masseter and zygomaticus. These points were marked with pins and measured in relation to a reference line between two anatomical landmarks near the origin and insertion of the respective muscle.

NEPs were located at 33%–38% (caninus), 69%–86% (levator anguli oculi medialis) and 0%–18% (zygomaticus) from the caudal landmark. The nasolabialis showed two innervations zones. Its NEPs were located at 47%–72% (dorsal muscle branch) and 52%–91% (ventral branch). All terminal nerve endings were found to run in rostral direction. The masseter showed numerous NEPs diffusely spread within the muscle belly. Therefore, calculation of relative positions was not performed.

The objective of this study was to describe the macro and microscopic morphology of these ligaments in domestic pigs, aiming to: (1) expand knowledge about the species; (2) provide anatomical references for advancing veterinary therapy and utilizing pigs as animal models in craniofacial research. Heads of young Sus scrofa domesticus were dissected to identify TMJ ligaments. Fragments of these ligaments were collected and processed for subsequent histological analysis with Haematoxylin and eosin staining. The results were qualitatively described. Pigs exhibited a TMJ reinforced by three individualized capsular ligaments: a lateral ligament, attaching to the ventral margin of the zygomatic process of the temporal bone and the lateral margin of the mandibular neck; a caudomedial ligament, attaching to the retroarticular process of the squamous part of the temporal bone and the caudomedial margin of the mandibular neck and a caudolateral ligament, attaching to the ventral margin of the base of the zygomatic process of the temporal bone and the caudal margin of the mandibular neck. The lateral ligament exhibited a greater constitution of dense irregular connective tissue, while the caudomedial and caudolateral ligaments showed a greater constitution of dense regular connective tissue. It is concluded that the TMJ of pigs presents one more ligament than horses, cattle, dogs, cats and what has been described for pigs themselves. We believe these results may contribute to the improvement of veterinary clinical and surgical therapy overall, as well as provide essential morphological information for a better interpretation and application of interspecies results in craniofacial research using pigs as an experimental model, as in the case of humans.","PeriodicalId":49290,"journal":{"name":"Anatomia Histologia Embryologia","volume":"53 5","pages":""},"PeriodicalIF":0.8,"publicationDate":"2024-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141876637","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
