Ogura cytoplasmic male sterility (CMS) lines play a crucial role in the utilization of heterosis. However, valuable traits, such as disease resistance genes from Ogura CMS hybrids, are challenging to incorporate for germplasm innovation, particularly in cabbage and broccoli. To date, the -mediated network regulating fertility restoration remains largely unexplored.

Endometrial injury is one of the leading causes of female infertility and is caused by intrauterine surgery, endometrial infection, repeated abortion, or genital tuberculosis. Currently, there is little effective treatment to restore the fertility of patients with severe intrauterine adhesions and thin endometrium. Recent studies have confirmed the promising therapeutic effects of mesenchymal stem cell transplantation on various diseases with definite tissue injury.

The changes of total nitrogen removal rate (TNRR), specific anammox activity (SAA) and nitrogen concentration under different current densities were analyzed, and then the effect of the optimal current density on the start-up of anammox in ESBR was explored. The results showed that ammonium nitrogen removal efficiency (92.

However, the regulatory function of tiRNAs in DR and its detailed mechanism remain unknown.

It is difficult to use either the olfactory function test or magnetic resonance imaging to directly assess the course of damage to olfactory nerves. Thallium-201 (Tl) olfacto-scintigraphy has been shown to be an able means for objectively assessing the olfactory nerve transport function.

Methods: Forty-nine patients from October 2008 to September 2012 with locally advanced stage esophageal carcinoma, clinical stage T2-4N0-3M0, who underwent preoperative chemoradiotherapy (pre-CRT) followed by esophagectomy were enrolled in our study. All patients underwent two FDG-PET scans to compare those results with the pathologic results.

Objective: The nasal cavity is an uncommon site for metastasis to develop and thus metastases arising from breast cancer are rarely observed. We report a case of a 61-year-old female with two-year history of breast cancer who presented with a nasal cavity that was diagnosed as metastatic breast carcinoma by histopathological analysis of the nasal cavity specimen.
Methods: We reviewed the clinical records of the patient and the appropriate world literature.
AMYLOIDOSIS is a benign process which can have systemic involvement. Though larynx is the common site of localized amyloidosis in the head and neck region,1 it was seldom reported with heterochronous implication of bilateral ventricles. Here we report a case of laryngeal amyloidosis heterochronously localized at bilateral ventricles with tracheobronchial involvement.

The authors conducted a systematic MEDLINE search of published articles. Two reviewers independently assessed the methodological quality of each study.

The variation in standardized uptake values of nodal metastasis among different NSCLC histological subtypes was also evaluated.
Methods: We retrospectively reviewed 75 NSCLC patients who had received FDG PET/CT before surgery.
A 49-year-old man was brought to our hospital because of lethargy. His medical history was hydrocephalus with ventriculoperitoneal shunt initially. The ventriculoperitoneal shunt was replaced several times owing to malfunction, and it was later replaced with a right-sided ventriculopleural shunt.

Materials And Methods: The authors conducted a systematic MEDLINE search of published articles. Two reviewers independently assessed the methodological quality of each study.
Objectives: Positron emission tomography (PET) using fluorodeoxyglucose (FDG) is useful for restaging renal cell carcinoma (RCC) and detecting metastatic diseases but is less satisfactory for detecting primary disease. We evaluated whether the integration of computed tomography (CT) scans with the PET system could increase the applicability of FDG-PET for RCC.
Methods: The MEDLINE databases were searched for relevant studies published since 2001.
The purpose of the present study was to conduct a systematic review and meta-analysis of the published literature to evaluate the diagnostic performance of fluorine-18 2-fluoro-2-deoxy-D-glucose (18F-FDG) PET in the pretherapeutic assessment of nodal staging in patients with colorectal cancer (CRC). We conducted a systematic MEDLINE search of articles in the published literature (last update, February 2012). Two reviewers independently assessed the methodological quality of each study.

Rationale And Objectives: Early detection of regional cerebral anomalies in acute carbon monoxide (CO) poisoning by (99m)Tc-hexamethylprophylene amine oxime (HMPAO) brain single photon emission computed tomography (SPECT) imaging has been reported previously. However, SPECT findings varied in these studies because of their small population sizes. In this study, we included 96 patients with acute CO intoxication and analyzed the regional perfusion changes in these patients by means of HMPAO brain SPECT.

Aims: To identify the presence of bacterial biofilms on mucosal specimens from chronic rhinosinusitis (CRS) patients, and evaluate their relationship with severity of CRS.
Methods: A prospective study of biofilms presence on 24 CRS patients compared with 12 controls was designed. The presence of biofilms was determined by scanning electron microscopy (SEM), and associations with the preoperative Lund-MacKay CT scores, Johansson endoscopic scores, and the history of ESS were assessed.

Method: Two hundred and fifty-three cases of nasal septum mass were treated by surgery in our department from March 1983 to August 2007. Their clinical data were retrospectively analyzed.
Background: There are congenital and acquired choanal atresias and many approaches have been used for their repair. We assessed the clinical effect of power instrument, endoscopic repair of acquired choanal stenosis and atresia.
Methods: Nineteen patients, aged from 32 to 61 years, with acquired choanal stenosis and atresia (from trauma in 5 cases and from radiotherapy after nasopharyngeal carcinoma in 14; 6 bilateral and 13 unilateral cases), underwent transnasal endoscopic repair of choanal stenosis and atresia.
