The natural plant flavonoid apigenin is a strong antioxidant that effectively delays peripheral neurodegenerative processes.

Anat Sci Int 2019 Apr 4. Epub 2019 Apr 4.

Department of Anesthesiology and Pain Medicine, College of Medicine, Kosin University, 262, Gamcheon-ro, Seo-gu, Busan, 49267, Korea.

Oxidative stress contributes to the progression of neurodegenerative diseases of the central and peripheral nervous systems, including Alzheimer's disease, Parkinson's disease, stroke, and diabetic neuropathy. Despite the greater capability of peripheral nerves to regenerate compared with those in the brain or spinal cord, chronic oxidative stress leads to irreversible neurodegeneration in peripheral nerves. Thus, many efforts have been made to defend against irreversible peripheral nerve degeneration and oxidative stress. Read More

A rare variation of the hemiazygos vein draining into the persistent left superior vena cava.

Anat Sci Int 2019 Feb 18. Epub 2019 Feb 18.

Department of Human Anatomy and Neurobiology, School of Basic Medical Science, Central South University, 172 Tongzipo Road, Changsha, 410013, Hunan, People's Republic of China.

During an educational dissection of a 72-year-old Chinese male cadaver, the hemiazygos vein (HAV) coursing the left side that drains into the persistent left superior vena cava was observed. The HAV was formed at the junction of the 9th to 11th right posterior intercostal veins, right subcostal vein, 5th to 11th left posterior intercostal veins, and left subcostal vein; it then ascended posteriorly to the thoracic aorta. After collecting the accessory hemiazygos vein, it crossed over the aorta and the pedicle of the left lung via the hemiazygos arch, then converged with a communicative branch (vein of Marshall) that emerged from the left brachiocephalic vein to form the persistent left superior vena cava and entered the pericardium at the level of the sixth thoracic vertebra.

Nerve to mylohyoid branched from the lingual nerve: previously undescribed case.

Anat Sci Int 2019 Feb 1. Epub 2019 Feb 1.

Seattle Science Foundation, 550 17th Avenue, Suite 600, Seattle, WA, 98122, USA.

The lingual nerve is a branch of the mandibular division of the trigeminal nerve. It descends medial and anterior to the inferior alveolar nerve through the pterygomandibular space, runs by the lingual plate and lingual crest at the lower third molar closely, and supplies sensory fibers to the anterior two-thirds of the tongue. Therefore, injury of this nerve is occasionally induced by wisdom tooth extraction and could lead to paralysis of the tongue. Read More

Authors:
Yousuke Tsuneoka

Anat Sci Int 2019 Jan 3;94(1):39-52. Epub 2018 Nov 3.

Department of Anatomy, School of Medicine, Faculty of Medicine, Toho University, 5-21-16 Omori-Nishi, Ota-ku, Tokyo, 143-8540, Japan.

The medial preoptic area (MPOA), an anterior part of the hypothalamus, is one of the most important areas for the regulation of instinctively motivated behaviors, such as parental behavior, mating behavior and aggression. Consistent with its role in reproductive behaviors, the MPOA abundantly expresses gonadal steroid hormone receptors and shows distinct sexual dimorphism in its morphology. Despite the functional importance of the MPOA, the anatomical demarcations of the mouse MPOA subregions have been confusing and remained undefined because of their heterogeneity and complexity.

Expression of α-synuclein is regulated in a neuronal cell type-dependent manner.

Anat Sci Int 2019 Jan 25;94(1):11-22. Epub 2018 Oct 25.

Department of Anatomy and Neurobiology, Graduate School of Medical Science, Kyoto Prefectural University of Medicine, Kawaramachi-Hirokoji, Kamikyo-ku, Kyoto, 602-8566, Japan.

α-Synuclein, the major component of Lewy bodies (LBs) and Lewy neurites (LNs), is expressed in presynapses under physiologically normal conditions and is involved in synaptic function. Abnormal intracellular aggregates of misfolded α-synuclein such as LBs and LNs are pathological hallmarks of synucleinopathies, including Parkinson's disease (PD) and dementia with Lewy bodies (DLB). According to previous studies using pathological models overexpressing α-synuclein, high expression of this protein in neurons is a critical risk factor for neurodegeneration. Read More

It consists of segmentation of tubules in serial paraffin sections of the testis by marking the basement membrane with periodic acid-Schiff or a fluorescent anti-laminin antibody followed by 3D reconstruction of tubules with high-performance software. Using this method, we analyzed testes from mice at different ages and accurately elucidated the 3D structure of seminiferous tubules, including the number and length of tubules as well as the numbers of connections with the rete testis, branching points, and blind ends.

Distribution of somatostatin-28 (1-12), calcitonin gene-related peptide, and substance P in the squirrel monkey brainstem: an immunocytochemical study.

Anat Sci Int 2019 Jan 26;94(1):86-100. Epub 2018 Jul 26.

Institute of Neuroscience of Castilla y León (INCYL), Laboratory of Neuroanatomy of the Peptidergic Systems (Lab. 14), University of Salamanca, Salamanca, Spain.

Using an immunocytochemical technique, we have studied the distribution of fibers and cell bodies containing somatostatin-28 (1-12) [SOM-28 (1-12)], calcitonin gene-related peptide (CGRP), and substance P (SP) in the brainstem of Saimiri sciureus. The distribution of the peptidergic cell bodies was very restricted: perikarya containing SOM-28 (1-12) were only observed in the substantia grisea centralis, while no immunoreactive cell bodies containing CGRP or SP were visualized. Fibers containing SOM-28 (1-12), CGRP, or SP were widely distributed in the brainstem: immunoreactive fibers containing SOM-28 (1-12) showed the most widespread distribution and were the most abundant.

Lorenzo Alibardi

Anat Sci Int 2018 Sep 22;93(4):548-558. Epub 2018 Jun 22.

Comparative Histolab Padova, Dipartimento di Biologia, Università di Bologna, via Selmi 3, 40126, Bologna, Italy.

The molting cycle of feathers includes an anagen (growth) stage, a likely catagen stage where the feather follicles degenerate, and a resting stage where fully grown feathers remain in their follicles and are functional before molting. However, the cytological changes involved in the resting and molting stages are poorly known, so the results of an ultrastructural analysis of these processes in adult chick feathers are presented here. The study showed that the dermal papilla shrinks, and numerous cells present increased heterochromatin and free collagen fibrils in the extracellular matrix. Read More

Effects of streptozotocin-induced diabetes on leg muscle contractile properties and motor neuron morphology in rats.

Anat Sci Int 2018 Sep 6;93(4):502-513. Epub 2018 Jun 6.

Department of Occupational Therapy, Graduate School of Kyorin University, 5-4-1 Simorenzyaku, Mitaka-city, Tokyo, 181-8612, Japan.

Skeletal muscle fiber subtypes are differentially sensitive to diabetes-related pathology; For example, fast-twitch muscles exhibit severe decreases in contraction force while slow-twitch muscles demonstrate prolonged half-relaxation time. However, such alterations have only been examined after a relatively short period following diabetes onset, with no information available regarding muscle damage caused by longer disease periods (>20 weeks). This study examined alterations in the contractile properties of the medial gastrocnemius (fast-twitch) and soleus (slow-twitch) muscles, as well as morphological changes in their motor neurons 12 and 22 weeks after diabetes onset.
