Expression patterns of the transcription factors Fezf1, Fezf2, and Bcl11b in the olfactory organs of turtle embryos.

Many tetrapod vertebrates have two distinct olfactory organs, the olfactory epithelium (OE) and vomeronasal organ (VNO). In turtles, the olfactory organ consists of two types of sensory epithelia, the upper chamber epithelium (UCE; corresponding to the OE) and the lower chamber epithelium (LCE; corresponding to the VNO). In many turtle species, the UCE contains ciliated olfactory receptor cells (ORCs) and the LCE contains microvillous ORCs.

Prevalence of skin diseases and prognosis of atopic dermatitis in primary school children in populated areas of Japan from 2010 to 2019: The Asa Study in Hiroshima, Japan.

Skin diseases are common in children. However, the prevalence of childhood skin diseases in Japan has not been reported extensively. In this study, dermatologists conducted face-to-face examinations of primary school children over a 10-year period to determine the prevalence of each skin disease.

The utility of atrial pacing for identifying the electrical breakthrough sites between the left atrium and pulmonary veins.

Background: Circumferential pulmonary vein (PV) isolation for atrial fibrillation (AF) is occasionally difficult to achieve because electrical breakthrough sites (EBSs) between the left atrium (LA) and PVs cannot be identified during ablation especially in the carina regions.

Methods: The left PVs (Lt.PVs) of 60 AF patients and the right PVs (Rt.

[A Case of Squamous Cell Carcinoma of the Esophagus with Achalasia -- Conversion from Chemoradiotherapy to Surgery].

The patient was a 67-year-old woman with achalasia and squamous cell carcinoma(SCC)of the esophagus. She presented with a difficulty in swallowing. The cancer was on the surface of the esophagus.

A case of lower-extremity deep burn wounds with periosteal necrosis successfully treated by use of allogenic cultured dermal substitute.

In patients with burns, bone exposure accompanies serious problems which occasionally lead to amputation. We present a case of an 82-year-old woman who sustained 22% of total body surface area flame burns on her bilateral lower extremities with bone exposure. Despite fascial excision and mesh skin graft, muscles, bones, and tendons were widely exposed on her right leg.

[Clinicopathological features of young patients with triple negative breast cancer].

This study investigated triple negative diagnoses that occurred in 27 (11%) out of 243 cases of breast cancer analyzed for the presence of estrogen receptor (ER), progesterone receptor( PgR), and human epidermal growth factor receptor 2 (HER 2). In 5 of the triple negative cases of breast cancer, the patients were young, under 35 years of age (average age of 29). In 22 of the cases, the women were 35 years or older (average age of 66).

Metastatic extramammary Paget's disease treated with paclitaxel and trastuzumab combination chemotherapy.

In the treatment of metastatic breast cancer, trastuzumab, a recombinant monoclonal antibody against human epidermal growth factor receptor 2 (HER2), is effective when tumor cells overexpress HER2 protein. Although some cases of extramammary Paget's disease (EMPD) also express HER2 protein, no case of EMPD has been reported to be treated with trastuzumab. A 75-year-old man who suffered from EMPD of the scrotum and inguinal region underwent a local excision and lymph node dissection.

Airway compression by the ascending aorta due to a thin thoracic cage.

An 89-year-old woman with dyspnea and disturbed consciousness due to hypoventilation was admitted to our hospital. Chest radiography showed no abnormal shadow, but she was intubated for deteriorated hypoventilation. Bronchoscopy demonstrated obstruction of the left main bronchus at the carina.

Surgery versus radiochemotherapy for resectable locally invasive pancreatic cancer: final results of a randomized multi-institutional trial.

Purpose: Although the outcome of surgery for locally advanced pancreatic cancer remains poor, it is improving, with 5-year survival up to about 10% in Japan. The preliminary results of our multi-institutional randomized controlled trial revealed better survival after surgery than after radiochemotherapy. We report the final results of this study after 5 years of follow-up.

Improved electrical and optical properties of Poly(3,4-ethylenedioxythiophene) via ordered microstructure.

Poly(3,4-ethylenedioxythiophene) (PEDOT) nanorods (80-150 nm in diameter) and nanospheres were synthesized through a self-assembly method using ferric chloride (FeCl(3)) and ammonium persulfate (APS) as oxidants, respectively, and camphorsulfonic acid (CSA) as the dopant. The PEDOT nanorods showed broader absorption bands, higher crystallinity and much higher room-temperature conductivity (approximately 300 S cm(-1)) than the PEDOT nanospheres. Such obviously distinct properties of these products were considered to be due to the much lower rate of polymerization with FeCl(3) than APS, which made the growth of PEDOT according to the suggested cylinder micelles more moderate and regular; as a result, the morphology of the microstructure changed and the crystallinity, the doping level, the molecular orderliness and the conductivity of PEDOT synthesized under lower rate of polymerization improved intensely at the same time.
