Splenic ectopic pregnancy: Rare location of ectopic pregnancy, how does it present?

Splenic ectopic pregnancy (SEP) is a rare high-mortality condition, particularly relating to life-threatening intraperitoneal bleeding due to a high risk of spontaneous rupture. Diagnosing in a timely fashion is extremely crucial and the patients could benefit from active treatment strategies and early management. In this article, we reviewed a case of 40 years-old female who complained of lower quadrant abdominal pain and amenorrhea with a history of intrauterine device (IUD) insertion for over 6 years.

Magnetic resonance imaging characteristics of glioblastoma of the optic pathway during adulthood.

Glioma has been previously known as the most common adult brain tumor. Glioma of the optic pathway is predominated by low-grade neoplasms. High-grade glioma in adults is extremely rare.

New cycloartane coronalyl acetate and other terpenoids with anti-inflammatory activity from the leaves of Vietnamese .

Phytochemical study on the methanolic extract of the leaves of Vietnamese plant Pierre ex Pit. has led to the isolation of a new cycloartane coronalyl acetate () together with six known ones, coronlolide methyl ester (), sootepin D (), coronalolide (), coronalolic acid (), sootepin G () and 23-deoxojessic acid (). Their structures were elucidated by a combination of 2 D NMR and HR-ESI-MS spectroscopies.

Non-conventional octameric structure of C-phycocyanin.

C-phycocyanin (CPC), a blue pigment protein, is an indispensable component of giant phycobilisomes, which are light-harvesting antenna complexes in cyanobacteria that transfer energy efficiently to photosystems I and II. X-ray crystallographic and electron microscopy (EM) analyses have revealed the structure of CPC to be a closed toroidal hexamer by assembling two trimers. In this study, the structural characterization of non-conventional octameric CPC is reported for the first time.

LED Lights Promote Growth and Flavonoid Accumulation of and Are Linked to the Enhanced Expression of Several Related Genes.

is a wild edible species and has been traditionally used for a wide range of diseases in many countries. Our research aims to find the optimal light-emitting diode (LED) lighting conditions to improve the growth and development of seedling at the acclimation stage. Two-month-old explants were cultured under the various lighting conditions including red (R), blue (B), BR (one blue: four red), BRW151 (one blue: five red: one white), BRW142 (one blue: four red: two white), and fluorescent lamp (FL).

Possible participation of acidic pH in bone resorption in middle ear cholesteatoma.

Objectives/hypothesis: The etiopathology of bone resorption in cholesteatoma is unclear. We studied pH in middle ear cholesteatoma tissue and the permeability of the cholesteatoma epithelium in an attempt to elucidate the mechanism of bone resorption in this disease.

Study Design: Laboratorial study.

Different expressions of erbB1/2 and tight junction proteins in hypertrophic inferior turbinates and nasal polyps.

Both inferior turbinate hypertrophy and nasal polyp formation entail the enlargement of the nasal mucosa caused by rhinosinusitis, but their macro/microscopic and clinical findings differ markedly. This study aimed at investigating differences in the expressions of erbB1/2 and the tight junction proteins, claudin-1 and tricellulin, in the two tissues. Ten inferior turbinates and ten nasal polyps were collected.

Thyroid gland cutaneous fistula secondary to a migratory fish bone: a case report.

Introduction: We report an extremely rare case of a migratory fish bone penetrating through the thyroid gland.

Case Presentation: A 56-year-old Japanese woman presented with a two-month history of a painless cutaneous fistula in her anterior neck with pus discharge. Endoscopic examinations showed no abnormality, but computed tomography revealed a bone-density needle-shaped foreign body sticking out anteroinferior from the esophagus wall, penetrating through her left thyroid lobe and extending nearly to the anterior cervical skin.

Synergism of Staphylococcus aureus colonization and allergic reaction in the nasal cavity in mice.

Background: The aim of this study is to investigate the reciprocal effect of Staphylococcus aureus colonization and allergic rhinitis in an allergy model of mice.

Methods: BALB/c mice with intraperitoneal ovalbumin (OVA) sensitization and/or intranasal S. aureus inoculation were prepared.

Efficacy of intratympanic steroid administration on idiopathic sudden sensorineural hearing loss in comparison with hyperbaric oxygen therapy.

Objectives/hypothesis: The efficacy of intratympanic steroid administration was examined in comparison with hyperbaric oxygen (HBO) therapy in patients with idiopathic sudden sensorineural hearing loss (ISSNHL).

Study Design: Retrospective study.

Methods: Two hundred seventy-six consecutive patients with ISSNHL (average hearing levels at 250, 500, 1,000, 2,000, and 4,000 Hz ≥ 40 dB; time from onset to treatment ≤30 days) were enrolled.

Expression of epidermal growth factors, erbBs, in the nasal mucosa of patients with chronic hypertrophic rhinitis.

Purpose: To investigate the expression of erbBs in the nasal mucosa of patients with chronic hypertrophic rhinitis.

Procedures: Inferior turbinates were collected from 12 turbinectomized patients with allergic and nonallergic chronic hypertrophic rhinitis. Differential cell counts in the peripheral blood and allergy tests were conducted before surgery.

Prediction model for hearing outcome in patients with idiopathic sudden sensorineural hearing loss.

The aim of this study is to develop a regression model for predicting hearing outcome in patients with idiopathic sudden sensorineural hearing loss (ISSNHL). A total of 174 consecutive patients with ISSNHL (average of the hearing levels at 250, 500, 1,000, 2,000, and 4,000 Hz was ≥40 dB; time from onset to treatment was ≤30 days) were retrospectively analyzed. They received steroid administration (400 mg/day of hydrocortisone sodium succinate followed by tapered doses) in combination with hyperbaric oxygen therapy.

A laryngographic and laryngoscopic study of Northern Vietnamese tones.

A laryngographic and laryngoscopic study of tone production in Northern Vietnamese, a language whose tones combine both fundamental frequency (f0) modulations and voice qualities (phonation types), was conducted with 5 male and 5 female speakers. Results show that the f0 contours of Northern Vietnamese tones are not only attributable to changes in vocal fold length and tension (partly through changes in larynx height), but that f0 drops are also largely caused by the glottal configurations responsible for the contrastive voice qualities associated with some of the tones. We also find that voice quality contrasts are mostly due to glottal constriction: they occasionally involve additional ventricular fold incursion and epiglottal constriction, but these articulations are usually absent.
