Subcutaneous adipose tissue (SAT), visceral adipose tissue (VAT), and fat beneath the dermis layer were investigated using a ball lens top hollow optical fiber Raman probe (BHRP). Hamsters were fed with trilinolein (TL) and tricaprin (TC) for six weeks and measurements were carried out every two weeks. The BHRP with an 800 μm diameter fused-silica ball lens was able to obtain information on the subcutaneous fat in a totally non-invasive manner. Changes in the concentration of TL and TC during the treatment were analyzed, and the relationship between fat accumulation and dietary fat was studied...

Serotonin [5-hydroxytryptamine (5-HT)] is involved in both motor and sensory functions in hollow organs, especially in the gastrointestinal tract. However, the involvement of 5-HT in visceral sensation of the urinary bladder remains unknown. Because distention-induced ATP release from the urothelium plays an essential role in visceral sensation of the urinary bladder, we investigated the regulation of urothelial ATP release by the 5-HT signaling system. RT-PCR and immunohistochemical analyses of the urothelium revealed specific expression of 5-HT1D and 5-HT4 receptors...

INTRODUCTION: In 1931, Simpson et al. coined the term "peritoneal carcinomatosis" to describe the regional spread of ovarian tumors as localized or extended with involvement of the peritoneal serous membrane and neighboring anatomical structures. Research into the origin of peritoneal carcinomatosis is based on two phases in a woman's life: EMBRYO DEVELOPMENT: During week 3, the bilaminar disc becomes a trilaminar disc called the mesoderm. Inside the lateral plate mesoderm, the coelomic cavity is divided into 2 layers: the parietal (somatic) mesoderm, which gives rise to the parietal peritoneum and pleural surfaces; and the visceral (splanchnic) mesoderm, which gives rise to the visceral peritoneum, visceral surface of the pleura, gonadal stroma, and the muscular layer of the hollow viscera and its mesenteries...

Male internal genitalia of eriophyoid mites comprise cuticle lined (anterior genital apodeme, genital chamber and ductus ejculatorius) and soft (paired vasa deferentia and single testis) organs. Three-dimensional reconstructions based on autofluorescence show that a thin-walled genital chamber is usually situated in a transverse plane and precisely copies the shape of the spermatophore. A thin vertical longitudinal plate (homologous to female longitudinal bridge) joins the genital chamber and ventral genital cuticle...

OBJECTIVE: Acupuncture is increasingly used as an alternative to medical therapy for various pain conditions. To study the effect of acupuncture in experimental and clinical studies, a control condition with sham acupuncture is needed. However, as such models have not been established in assessment of acupunctures effect against visceral pain, this study aimed to validate a new method for blinded sham acupuncture in experimental rectal pain. METHODS: Fifteen subjects underwent a sequence of either sham or real acupuncture in randomized order...

The celiac axis (CA) and its branches are critically important arteries that supply blood to the vital solid and hollow abdominal viscera of the foregut. There are many potential anatomic configurations, with up to half the population having a variation from the classic pattern of the CA bifurcating into the hepatosplenic trunk and left gastric artery. These configurations result from permutations in the fusion of the paired dorsal aortas during the first trimester. Despite the short length of the CA, it is affected by a wide range of pathologic conditions, including mesenteric ischemia due to intrinsic occlusion (secondary to causes such as atherosclerosis or thromboembolic events) and extrinsic compression from masses or the median arcuate ligament...

INTRODUCTION: Pneumoperitoneum, observed by radiography, is typically associated with the perforation of hollow viscous. More than 90% of all cases of pneumoperitoneum are the result of a gastrointestinal tract perforation. These patients usually present with signs of acute peritonitis and require immediate surgical exploration and intervention. However, rare cases of idiopathic spontaneous pneumoperitoneum do occur without any indication of visceral perforation and other known causes of the free intraperitoneal gas...

Visceral pain has been defined as a pain resulting from activation of pain receptors localized in mucous membrane, serous membrane, and smooth muscles of hollow organs. The great majority of these organs are innervated by parasympathetic and sympathetic outflows. Afferent nerve fibres are involved in conduction of both acute and persistent pain and hyperalgesia. Visceral pain differs significantly from other types of pain in the way it originates and in clinical presentation. It can be misleading as a symptom, producing several problems in the diagnostic process...

We describe the laparoscopic management of diaphragmatic hernia (DH) caused by vertebral pedicle screw displacement. A 58-year-old woman underwent surgery for scoliosis and underwent posterior pedicle screw fixation. In the first postoperative (PO)day, she developed mild dyspnea. An anteroposterior chest radiograph revealed bilateral pleural effusion, which was more pronounced on the left side. A thoracoabdominal computed tomography (CT) scan, performed in the second PO day, revealed a solid mass in the pleural cavity that was associated with screw displacement, which had also entered into the peritoneal cavity without apparent other lesion of hollow and solid viscous...

A sensory role for ATP was proposed long before general acceptance of its extracellular role. ATP activates and sensitizes signal transmission at multiple sites along the sensory axis, across multiple synapses. P2X and P2Y receptors mediate ATP modulation of sensory pathways and participate in dysregulation, where ATP action directly on primary afferent neurons (PANs), linking receptive field to CNS, has received much attention. Many PANs, especially C-fibers, are activated by ATP, via P2X3-containing trimers...

The small intestine is the third in frequency intraperitoneal organ which is injured after blunt trauma of the abdomen. In most of the cases, this type of injuries is accompanied by other injuries, which make it more difficult to diagnose. Failure of diagnosis and delay in treating these injuries significantly increase the morbidity and mortality of these patients. Abdominal visceral injuries after flipping the handlebar of the bike are common in children. Such injuries can cause injury to both solid and hollow abdominal viscera...
