Nutritional Quality and Physical Characteristics of Soluble Proteins Recovered from Silver Carp.

Unlabelled: The objective of this study was to evaluate the nutritional quality and physical characteristics of soluble proteins separated from silver carp at 4, 20, and 40 °C. Ground silver carp was diluted, and soluble proteins were separated by centrifugation and dried. The proximate composition (dry wt) of the protein powders averaged 82.

Effects of starch concentration on calcium-enhanced black bullhead catfish protein gels.

Calcium-enhanced protein recovered from black bullhead catfish was used to develop gels containing increasing amounts of potato starch (0-20 g/kg protein paste) and the effects of starch on functional, textural, and color properties were tested. Energy required to unfold protein groups was greater with the addition of 5 g starch/kg protein paste. Gels containing starch were harder, chewier, and less springy ( < .

Calcium hydroxide as a processing base in alkali-aided pH-shift protein recovery process.

Background: Protein may be recovered by using pH shifts to solubilize and precipitate protein. Typically, sodium hydroxide is used as the processing base; however, this has been shown to significantly increase sodium in the final recovered protein.

Results: Protein was extracted from black bullhead catfish (Ameiurus melas) using a pH-shift method.

Influence of pre-cooking protein paste gelation conditions and post-cooking gel storage conditions on gel texture.

Background: Gelation conditions affect the setting of myofibrillar fish protein gels. Therefore the impact of widely applied pre-cooking gelation time/temperature strategies and post-cooking period on the texture and color of final protein gels was determined. Four pre-cooking gelation strategies (no setting time, 30 min at 25 °C, 1 h at 40 °C or 24 h at 4 °C) were applied to protein pastes (fish protein concentrate and standard functional additives).

Osteoplastic flap approach versus orbitotomy in case of orbitofrontal cholesterol granuloma.

A 44-year-old man developed a slow-growing painless left superolateral orbital mass that extended into the frontal sinus with a complaint of ptosis. Magnetic resonance imaging revealed a heterogenous hyperintense lesion confined to the left frontal bone and superior orbit. The osteoplastic frontal sinus approach was performed to drain supraorbital cholesterol granuloma cyst and for curetting the capsule.

Coexistence of gastrointestinal stromal tumors (GISTs) and pheochromocytoma in three cases of neurofibromatosis type 1 (NF1) with a review of the literature.

It is well known that neurofibromatosis type 1 (NF1) is uncommonly associated with pheochromocytoma development and also, to a larger extent, with gastrointestinal stromal tumors (GISTs). We herein document three cases with the rare condition of NF1 coexisting with GIST and pheochromocytoma, while one of them also has a composite tumor and another has papillary thyroid carcinoma.

pH shift protein recovery with organic acids on texture and color of cooked gels.

Background: Isoelectric solubilization and precipitation (ISP) processing uses pH shifts to separate protein from fish frames, which may increase commercial interest for silver carp. Texture and color properties of gels made from silver carp protein recovered at different pH strategies and organic acid types were compared. ISP was applied to headed gutted silver carp using 10 mol L(-1) sodium hydroxide (NaOH) and either glacial acetic acid (AA) or a (1:1) formic and lactic acid combination (F&L).

Respiratory epithelial adenomatoid hamartoma: a rare nasopharyngeal mass lesion.

Respiratory epithelial adenomatoid hamartoma (REAH) is a rare and nonneoplastic lesion of upper respiratory tract characterized by an abnormal mixture of tissues which are peculiar to the involved anatomic region. The most common site reported is nasal cavity and its nasopharyngeal origin is extremely rare. The lesion can be confused with a variety of benign and malignant entities.

Interobserver agreement in salivary gland neoplasms by telepathology: An analysis of 47 cases.

Objective: To assess the discrepancies that prevailed among the members of the Head and Neck Pathology Working Group in Turkey in diagnosing salivary gland tumors, classified primarily according to myoepithelial origin, by utilizing telepathology.

Study Design: At least 4 representative images were obtained from each case of a total of 47 salivary gland tumors, and these were studied by 14 participants. The tumors examined were classified into 2 categories under behavior as malignant or benign, and also grouped into 2 categories under differentiation: those showing and those not showing myoepithelial differentiation.

Objectives: This study aims to evaluate the accuracy ratio of fine needle aspiration (FNA) cytology in the diagnosis of non-thyroidal head and neck masses.

Patients And Methods: Between 2000 January and 2003 December, the pathology reports of 571 patients (297 males, 274 females; mean age 45 years; range 4 to 83 years) with non-thyroidal head and neck masses who underwent FNA cytology during a four year period were retrospectively analyzed. Cytopathological and histopathological results of the samples were recorded.

The value of touch imprint cytology of core needle biopsy in the diagnosis of spinal lesions.

Aim: We aimed to investigate the contribution of the touch imprint cytology (TIC) of core needle biopsies (CNBs) to the diagnosis in spinal lesions.

Material And Methods: Sixty cases with spinal CNB and TIC were included in the study. Hematoxylin and Eosin (H&E) and May-Grunwald- Giemsa (MGG) stained TIC slides and CNB of each case were blindly reevaluated by two pathologists.

Detection of prostate cancer with magnetic resonance imaging: optimization of T1-weighted, T2-weighted, dynamic-enhanced T1-weighted, diffusion-weighted imaging apparent diffusion coefficient mapping sequences and MR spectroscopy, correlated with biopsy and histopathological findings.

Purpose: The aim of this study was to optimize and predict the most efficient magnetic resonance imaging (MRI) sequences; T1-weighted (T1W), T2-weighted (T2W), dynamic contrast-enhanced (DCE) T1W, diffusion-weighted imaging (DWI) apparent diffusion coefficient (ADC) mapping sequences and proton MR spectroscopy (H-MRS) for the detection of prostate cancer.

Basal cell adenoma with extensive squamous metaplasia and cellular atypia: a case report with cytohistopathological correlation and review of the literature.

Basal cell adenoma (BCA) is a rare benign basaloid neoplasm of the salivary gland. There are four histopathological types of BCA: solid, tubular, trabecular, and membranous. It is known that focal squamous metaplasia may be seen in some BCAs, but it is rare to see extensive squamous metaplasia, especially with cellular atypia.

Methods: The Ankara Pediatric Pathology Working Group collected databases of pediatric solid tumors from six pediatric reference centers in order to analyze the incidence, distribution and some epidemiologic characteristics of the tumors and to establish a multicenter database for further studies. A five-year retrospective archive search was carried out.

Survival of Listeria innocua in rainbow trout protein recovered by isoelectric solubilization and precipitation with acetic and citric acids.

During mechanical fish processing, a substantial amount of protein is discarded as by-products. Isoelectric solubilization and precipitation (ISP) is a process that uses extreme pH shifts to solubilize and precipitate protein from by-products to recover previously discarded protein. Typically, strong acids are used for pH reduction, but these acids do not have a pasteurization effect (6 log reduction) on bacterial load; therefore, organic acids were used during ISP processing to test the impact on Listeria innocua concentrations.

Intrathyroidal oncocytic parathyroid adenoma: a diagnostic pitfall on fine-needle aspiration.

Oncocytic parathyroid adenoma is a rarely seen benign neoplasm of the parathyroid and intrathyroidal location of this lesion is also uncommon. It can be easily misdiagnosed as Hürthle cell thyroid neoplasm on fine-needle aspiration (FNA). Here, an intrathyroidal oncocytic parathyroid adenoma in a 32-year-old male is reported.
