Reliability of Bigliani's Classification using Magnetic Resonance Imaging for Determination of Acromial Morphology. Malays Orthop J 2022; 16:44-49. [PMID: 36589385 PMCID: PMC9791892 DOI: 10.5704/moj.2211.008] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2021] [Accepted: 02/10/2022] [Indexed: 12/13/2022] Open
Abstract
Introduction Bigliani classification is used for determination of acromial morphology, but poor inter-observer reliability has been reported on conventional radiographs. This study aims to assess inter- and intra-observer reliability using magnetic resonance imaging (MRI). Materials and methods Forty consecutive patients diagnosed with subacromial impingement syndrome were included to study. All subjects underwent standard shoulder MRI scan and acromial shape was evaluated by nine observers of different level of expertise (three attending surgeons, three senior orthopaedic residents and three radiologists). A second set of evaluation was performed in order to assess intra-observer reproducibility. Kappa (κ) coefficient analyses both for interobserver reliability and intra-observer reproducibility were then performed. Results Overall inter-observer agreement among nine observers was fair (κ=0.323). κ values for all 4 individual types ranged from 0.234 to 0.720 with highest agreement for type 4 and lowest agreement for type 3. Second evaluation did not result with an increase of inter-observer agreement (κ=0.338, fair). The κ coefficients for intra-observer reproducibility of nine observers ranged from 0.496 to 0.867. Overall intra-observer reproducibility was substantial. Comparison of inter- and intra-observer reliability among three groups showed no significant difference (p=0.92 and 0.22, respectively). Conclusion Results showed that MRI did not show superior reliability compared to conventional radiographs. Moreover, inter- and intra-observer agreement did not differ between observers of different level of expertise. Findings of present study suggest that despite a sophisticated imaging modality like MRI, Bigliani's classification apparently lacks accuracy and additional criteria, or different assessment methods are required to assess acromial morphology for clinical guidance.

Intercellular bridges coordinate the transition from pluripotency to meiosis in mouse fetal oocytes. SCIENCE ADVANCES 2021; 7:7/15/eabc6747.

Abstract
Meiosis is critical to generating oocytes and ensuring female fertility; however, the mechanisms regulating the switch from mitotic primordial germ cells to meiotic germ cells are poorly understood. Here, we implicate intercellular bridges (ICBs) in this state transition. We used three-dimensional in toto imaging to map meiotic initiation in the mouse fetal ovary and revealed a radial geometry of this transition that precedes the established anterior-posterior wave. Our studies reveal that appropriate timing of meiotic entry across the ovary and coordination of mitotic-meiotic transition within a cyst depend on the ICB component Tex14, which we show is required for functional cytoplasmic sharing. We find that Tex14 mutants more rapidly attenuate the pluripotency transcript Dppa3 upon meiotic initiation, and Dppa3 mutants undergo premature meiosis similar to Tex14 Together, these results lead to a model that ICBs coordinate and buffer the transition from pluripotency to meiosis through dilution of regulatory factors.

Comprehensive multi-technique approach reveals the high diversity of microcystins in field collections and an associated isolate of Microcystis aeruginosa from a Turkish lake. Toxicon 2019; 167:87-100. [PMID: 31181296 DOI: 10.1016/j.toxicon.2019.06.006] [Citation(s) in RCA: 21] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2019] [Revised: 05/23/2019] [Accepted: 06/03/2019] [Indexed: 12/21/2022]
Abstract
Microcystins (MCs) are hepatotoxic and potentially carcinogenic cyanotoxins. They exhibit high structural variability, with nearly 250 variants described to date. This variability can result in incomplete detection of MC variants during lake surveys due to the frequent use of targeted analytical methods and a lack of standards available for identification and quantitation. In this study, Lake Uluabat in Turkey was sampled during the summer of 2015. Phylogenetic analysis of the environmental mcyA sequences suggested Microcystis spp. were the major MC contributors. A combination of liquid chromatography-tandem mass spectrometry (LC-MS/MS), liquid chromatography with UV detection and mass spectrometry (LC-UV-MS), and a novel liquid chromatography-high resolution mass spectrometry (LC-HRMS) method, together with thiol and periodate reactivity, revealed more than 36 MC variants in the lake samples and a strain of M. aeruginosa (AQUAMEB-24) isolated from Lake Uluabat. Only MCs containing arginine at position-4 were detected in the culture, while MC-LA, -LY, -LW and -LF were also detected in the lake samples, suggesting the presence of other MC producers in the lake. The previously unreported MCs MC-(H2)YR (dihydrotyrosine at position-2) (17), [epoxyAdda5]MC-LR, [DMAdda5]MC-RR (1) and [Mser7]MC-RR (8) were detected in the culture and/or field samples. This study is a good example of how commonly used targeted LC-MS methods can underestimate the diversity of MCs in freshwater lakes and cyanobacteria cultures and how untargeted LC-MS methods can be used to comprehensively assess MC diversity present in a new system.

Temperature Effects Explain Continental Scale Distribution of Cyanobacterial Toxins. Toxins (Basel) 2018; 10:toxins10040156.

Abstract
Insight into how environmental change determines the production and distribution of cyanobacterial toxins is necessary for risk assessment. Management guidelines currently focus on hepatotoxins (microcystins). Increasing attention is given to other classes, such as neurotoxins (e.g., anatoxin-a) and cytotoxins (e.g., cylindrospermopsin) due to their potency. Most studies examine the relationship between individual toxin variants and environmental factors, such as nutrients, temperature and light. In summer 2015, we collected samples across Europe to investigate the effect of nutrient and temperature gradients on the variability of toxin production at a continental scale. Direct and indirect effects of temperature were the main drivers of the spatial distribution in the toxins produced by the cyanobacterial community, the toxin concentrations and toxin quota. Generalized linear models showed that a Toxin Diversity Index (TDI) increased with latitude, while it decreased with water stability. Increases in TDI were explained through a significant increase in toxin variants such as MC-YR, anatoxin and cylindrospermopsin, accompanied by a decreasing presence of MC-LR. While global warming continues, the direct and indirect effects of increased lake temperatures will drive changes in the distribution of cyanobacterial toxins in Europe, potentially promoting selection of a few highly toxic species or strains.

Abstract
Objectives The purpose of this study was to compare the shear bond strength of a novel repair system, Nova Compo SF with Ceramic Repair, Ivoclar, to computer-aided design/computer-assisted manufacturing (CAD/CAM) restorative materials (IPS e.max CAD and Empress CAD). Materials and Methods The specimens of each CAD/CAM restorative material were randomly divided into two subgroups of nine specimens, using one of two repair systems. All specimens were etched with hydrofluoric acid and rinsed under a water spray for 10 s, then air-dried for 10 s. Next, repair systems were applied according to the manufacturer's instructions. All specimens were stored in distilled water at 37°C for 24 h and then additionally aged for 5000 thermal cycles. A shear bond strength test was performed using a universal testing machine. Each fracture type was examined under a stereomicroscope at ×12.5 magnification. A two-way ANOVA test was used to detect significant differences between the CAD/CAM restorative materials and the composite repair systems. Subgroup analyses were performed using Tukey's honest significant difference. Results No statistically significant differences were observed between the repair systems (P = 0.9). The bond strength values from Empress CAD were statistically higher than those from e.max CAD (P < 0.05). Conclusions Within limitations, SuperFlow may be an alternative to the ceramic repair materials we routinely used in the clinic. Empress CAD can be preferable to e.max CAD in terms of esthetically suitable clinical indications.

Abstract
This study aimed to develop a scale called Tongue Thrust Rating Scale (TTRS), which categorised tongue thrust in children in terms of its severity during swallowing, and to investigate its validity and reliability. The study describes the developmental phase of the TTRS and presented its content and criterion-based validity and interobserver and intra-observer reliability. For content validation, seven experts assessed the steps in the scale over two Delphi rounds. Two physical therapists evaluated videos of 50 children with cerebral palsy (mean age, 57·9 ± 16·8 months), using the TTRS to test criterion-based validity, interobserver and intra-observer reliability. The Karaduman Chewing Performance Scale (KCPS) and Drooling Severity and Frequency Scale (DSFS) were used for criterion-based validity. All the TTRS steps were deemed necessary. The content validity index was 0·857. A very strong positive correlation was found between two examinations by one physical therapist, which indicated intra-observer reliability (r = 0·938, P < 0·001). A very strong positive correlation was also found between the TTRS scores of two physical therapists, indicating interobserver reliability (r = 0·892, P < 0·001). There was also a strong positive correlation between the TTRS and KCPS (r = 0·724, P < 0·001) and a very strong positive correlation between the TTRS scores and DSFS (r = 0·822 and r = 0·755; P < 0·001). These results demonstrated the criterion-based validity of the TTRS. The TTRS is a valid, reliable and clinically easy-to-use functional instrument to document the severity of tongue thrust in children.

Abstract
Cerebral palsy (CP) is a group of permanent sensorimotor impairments. Children with CP have various feeding difficulties including chewing disorder, which may affect their nutritional status. Functional Chewing Training (FuCT) was designed as a holistic approach to improve chewing function by providing postural alignment, sensory and motor training, and food and environmental adjustments. This study aimed to investigate the effect of FuCT on chewing function in children with CP. This study was designed as a double-blind, randomised controlled trial. Eighty CP children with chewing disorder were randomised and split between the FuCT group (31 males, 19 females; mean age 3·5 ± 1·9 years) and the control group (16 males, 14 females; 3·4 ± 2·3 years) receiving traditional oral motor exercises. Each group received the training programme for 12 weeks with weekly follow-up and with two evaluations at baseline and end of 12 weeks. Chewing function was evaluated by analysing video recordings and scored with the Karaduman Chewing Performance Scale (KCPS). The Behavioral Pediatrics Feeding Assessment Scale (BPFAS) was used to evaluate feeding behaviours of children. A significant improvement was observed in KCPS scores at 12 weeks after training in the FuCT group (P < 0·001), but no change was found in the control group (P = 0·07). A significant improvement was detected in all parameters of BPFAS at 12 weeks after training in the FuCT group (P < 0·001) and in four parameters of BPFAS in the control group (P = 0·02, P = 0·02). FuCT is an effective method to improve chewing function compared with traditional oral motor exercises.

Abstract
Early and reliable screening for oropharyngeal dysphagia (OD) symptoms in at-risk populations is important and a crucial first stage in effective OD management. The Eating Assessment Tool (EAT-10) is a commonly utilized screening and outcome measure. To date, studies using classic test theory methodologies report good psychometric properties, but the EAT-10 has not been evaluated using item response theory (e.g., Rasch analysis). The aim of this multisite study was to evaluate the internal consistency and structural validity and conduct a preliminary investigation of the cross-cultural validity of the EAT-10; floor and ceiling effects were also checked. Participants involved 636 patients deemed at risk of OD, from outpatient clinics in Spain, Turkey, Sweden, and Italy. The EAT-10 and videofluoroscopic and/or fiberoptic endoscopic evaluation of swallowing were used to confirm OD diagnosis. Patients with esophageal dysphagia were excluded to ensure a homogenous sample. Rasch analysis was used to investigate person and item fit statistics, response scale, dimensionality of the scale, differential item functioning (DIF), and floor and ceiling effect. The results indicate that the EAT-10 has significant weaknesses in structural validity and internal consistency. There are both item redundancy and lack of easy and difficult items. The thresholds of the rating scale categories were disordered and gender, confirmed OD, and language, and comorbid diagnosis showed DIF on a number of items. DIF analysis of language showed preliminary evidence of problems with cross-cultural validation, and the measure showed a clear floor effect. The authors recommend redevelopment of the EAT-10 using Rasch analysis.

Abstract
Tanycytes are special ependymal cells located in the ventrolateral wall and floor of the third ventricle having processes extending nuclei that regulate reproductive functions and around of vessels in median eminance. The aquaporins (AQPs) are a family of transmembrane proteins that transport water and glycerol. AQP-7 and -9 are permeable to other small molecules as glycerol and therefore called aquaglyceroporins. In this study, we aimed to show localization of AQP-7 and -9 in epithelial cells of choroid plexus and tanycytes during female mouse estrus cycle. AQP-7 and -9 proteins were detected in α2 and β1 tanycytes in prœstrus stage. Interestingly, there is no staining in estrus stage in any type of tanycytes. We observed weak immunoreactivity in α1, α2 and β1 tanycyte cells in metestrus stage for AQP-7 and α1 for AQP-9 protein. AQP-7 and -9 showed intense immunoreactivity in α2, β1 and β2 tanycyte cells during diestrus stage. Consequently, AQP-7 and -9 showed differential staining pattern in different stages of mouse estrus cycle. In the light of our findings and other recent publications, we suggest that AQP-7 and -9-mediated glycerol transport in tanycyte cells might be under hormonal control to use glycerol as a potential energy substrate during mouse estrus cycle.

Abstract
OBJECTIVE To investigate serum concentration of nesfatin-1 in underweight children who have poor appetite, and its association with anthropometric markers of malnutrition. PATIENTS AND METHODS We recruited 50 underweight children and adolescents (aged 2-18 years) who presented with loss of appetite. Thirty age- and sex-matched controls were also included in the study. Fasting serum nesfatin-1 concentrations were measured by using Enzyme-Linked Immunosorbent Assay (ELISA) technique. RESULTS Mean nesfatin-1 level was significantly higher in underweight children when compared to controls (p<0.001). There was no correlation between serum nesfatin-1 levels and anthropometrics markers. CONCLUSIONS Our results suggest that nesfatin-1 might have an important role in regulation of food intake and pathogenesis of loss of appetite in children.

Abstract
OBJECTIVE The influence of prostatic acid phosphatase (PAP) and human chorionic gonadotropin (HCG), tumor markers have been investigated on human erythrocyte carbonic anhydrase (HCA-I and HCA-II) and bovine erythrocyte (BCA) and bovine lung carbonic anhydrase (CA-IV) in vitro. BACKGROUND Tumor markers are substances that can often be detected in higher-than-normal amounts in the blood, urine, or body tissues of some patients with certain types of cancer. Tumor markers are produced either by the tumor itself or by the body in response to the presence of cancer or certain benign (noncancerous) conditions. In addition to their role in cancer diagnosis, some tumor marker levels are measured before treatment to help doctors plan appropriate therapy. RESULTS AND CONCLUSION All of the tumor markers were determined to have inhibition effect, on human CA-I, CA-II, bovine erythrocyte CA (BCA) and bovine lung CA-IV isoenzymes. The effect of each tumor marker on CA was investigated by Wilbur-Andersen method modified by Rickly et al Inhibition effects of two different tumor markers on human CA-I, CA-II, bovine erythrocyte CA (BCA) and bovine lung CA-IV isoenzymes were determined by using the CO2-Hydratase method by plotting activity % vs (tumor markers). I50 values of tumor markers exhibiting inhibition effects were found by means of these graphs (Tab.1, Fig. 2, Ref. 20).

Abstract
The megalencephaly, polymicrogyria, polydactyly, and hydrocephalus (MPPH) syndrome is quite rarely seen. The four main findings in this syndrome may be accompanied by severe psychomotor retardation, blindness, hypotonia, convulsions, and facial dysmorphism. In this paper, we present a female newborn at 39 weeks gestational age born to parents who are first degree cousins. Beside the facial dysmorphism and four main features of the MPPH syndrome, the findings on the physical examination of the patient were, hypertonicity, occipital encephalocele, cleft palate, and multiple polyps in the tongue. The presence of occipital encephalocele, cleft palate, and polyps in the tongue in this patient was not reported previously in the literature.

Abstract
Simpson-Golabi-Behmel syndrome is a clinical condition described by Simpson, characterized with multiple congenital anomalies and caused by Glypican 3 (GPC3) mutations of the X-linked gene. Typical findings such as overgrowth, hypoplastic changes of hands and feet, visceromegaly, cleft palate and macrocephalic distinctive facial features and multiple organ anomalies might be observed. GPC3 mutation is claimed to generally cause metopic synostosis. This case was reported because even though a lot of anomalies accompanying Simpson-Golabi-Behmel syndrome had been noticed, combination of metopic synostosis, has not been reported before.

Abstract
AIM This study aimed to evaluate the preoperative and postoperative oxidative status of children with chronic adenotonsillar hypertrophy. MATERIALS AND METHODS The study comprised 25 patients with indications for tonsillectomy and/or adenoidectomy following a diagnosis of chronic adenotonsillar hypertrophy and 25 age-gender matched control patients were included to the study. Blood samples were taken from the patients preoperatively and at four weeks postoperatively. Preoperative and postoperative serum total oxidant (TOS) and total antioxidant (TAS) levels were measured and the oxidative stress index (OSI) was calculated. RESULTS The serum total oxidant level and oxidant stress index values in the preoperative and postoperative periods of the patients were found to be significantly high compared to those of the control group. While the preoperative serum total oxidant level values were found to be significantly high compared to the postoperative values, no statistical significance was found between the total antioxidant and oxidative stress index values. CONCLUSION The development of chronic adenotonsillar hypertrophy plays a role in oxidative status and therefore, to neutralize high levels of oxidants in patients, the use of antioxidants for a period preoperatively and postoperatively is thought to be necessary.

Abstract
Pica is defined as developmentally inappropriate consumption of nonnutritive substances for at least 1 month. There are a few studies on serum trace element levels of patients with pica. The literature contains contracting data on the levels of oxidative stress and antioxidant levels in patients with iron-deficiency anemia (IDA). The effect of pica on oxidative stress and antioxidant capacity has not been investigated yet. The present study evaluated the effects of pica and IDA on oxidative stress and antioxidant capacity as well as on the levels of trace elements including serum zinc and selenium in 47 children with IDA plus pica, 22 children with IDA only and 21 nonanemic children as controls. The results demonstrated significantly lower levels of serum selenium and zinc in pica and IDA groups compared to the control group. Total oxidant levels were highest in the pica group and consistently, the lowest total antioxidant capacity was observed again in the pica group. Comparison of pica and IDA groups yielded significantly lower levels of total antioxidant levels and significantly higher oxidative stress index in the pica group. Consequently, it is thought that the detrimental effects of pica within the organism were mediated by adverse impacts on antioxidant capacity and oxidative stress. These effects should be kept in mind while managing patients with pica.

Abstract
PURPOSE The aim of this study was to verify whether FV Leiden, PT G20210A, MTHFR C667T or MTHFR A1298C mutations influence the risk of recurrent fetal loss in a sample of Turkish women who had experienced recurrent fetal loss and to evaluate whether the aforementioned thrombophilias and recurrent fetal loss may affect the birth weight of subsequent pregnancies. METHODS Fifty-eight women with recurrent pregnancy loss and 30 women with successful pregnancies were evaluated. RESULTS The average birth weights for infants of all women in the study group and for infants of thrombophilia-positive women in the study group were markedly lower than the birth weight of infants in the control group (p<0.001 and p<0.001, respectively). CONCLUSION Successful pregnancies in women with a history of recurrent fetal losses may be associated with lower birth weights compared to controls, irrespective of thrombophilia status. This conclusion warrants further research.

Abstract
Management of preterm premature rupture of membranes (PPROM) is a very challenging issue for the obstetricians. We report two cases of PPROM occurring in early gestation remote from term (both < 26 weeks) with exiguous amniotic fluid (amniotic fluid index of < or =2 cm) that were managed successfully by conservative treatment and resulted in a latency period of almost two months. This treatment option might be feasible in carefully selected patients following meticulous evaluation and warrants further research.

Abstract
The epithelial cells of the mouse endometrium comprises the recurring physiologic changes such as proliferation and apoptosis induced by the reproductive hormones throughout the estrus cycle. The c-Abl is a protein tyrosine kinase, localized in the different cellular compartments such as nucleus, cytoplasm, mitochondria, and endoplasmic reticulum, interacts with different cellular proteins, including signaling adaptors, kinases, phosphatases, cell-cycle regulators, transcription factors and cytoskeletal proteins. Our hypothesis is that the c-Abl expression in the mouse uterine epithelium shows cyclic changes during the estrus cycle that is involved in regulation of the endometrial epithelial cells. The regulation of c-Abl gene and protein expression in the uterus of intact animals in the different cycle phases was investigated using immunohistochemistry, western blot and semi-quantitative RT-PCR. The immunohistochemistry results revealed that the luminal and the glandular epithelium (LE) and (GE), respectively, showed gradually increase in the expression of c-Abl from the proestrus (P) to the metestrus and followed by a decrease in the diestrus (D). c-Abl immunoreactivity was detected in the both LE and GE cells, especially the LE showed diminished the c-Abl protein expression on the D phase and the minimal value was detected on the P day. The c-Abl protein level in the LE was increased during the M, presenting a high correlation with the hormonal level of this cell type. The result of c-Abl RT-PCR analysis was compatible with pattern of c-Abl protein expression. In conclusion, the stage-specific protein pattern of the mammalian c-Abl tyrosine kinase presented a good correlation with the mouse estrus cycle and may have a regulative function during the uterine remodeling.

Abstract
Contamination of the aquatic environment with various concentrations of pollutants results in unexpected threats to humans and wildlife. The consequences of exposure and metabolism of pollutants/xenobiotics, especially carcinogens and mutagens, can be suitably assessed by investigating severe events, such as DNA damage; for example, DNA adducts and DNA strand breaks. One of the commonly used techniques to detect DNA damage in aquatic organisms is single-cell gel electrophoresis (comet assay). This study was carried out using Cyprinus carpio in order to identify the possible pollution in Lake Mogan, near Ankara, Turkey, where the city's sewer system and pesticides used in agriculture are believed to be the common causes of pollution. From the comet assay, the tail length (micrometer), tail intensity (%), and tail moment values of fish caught from Lake Mogan were found to be 31.10 ± 10.39, 7.77 ± 4.51, 1.50 ± 1.48, respectively, whereas for clean reference sites they were found to be 22.80 ± 1.08, 3.47 ± 1.59, 0.40 ± 0.51, respectively. The values are statistically different from each other (p < 0.0001, p < 0.0001, and p = 0.0013, respectively). These results indicate that Lake Mogan may be polluted with substances that have genotoxic effects and constitute an early warning for the lake system. Further detailed research is needed to establish the source of the pollution and the chemicals responsible.

Abstract
This study was conducted to audit maternal seafood intake awareness during pregnancy and to determine whether there is an association between fish consumption and various pregnancy outcomes. In total, 553 low-risk and healthy pregnant women were given a questionnaire concerning fish consumption. Pregnant women who developed gestational diabetes mellitus, pre-term labour-birth, macrosomia, low birth weight and small for gestational age were analysed. Fatty fish consumers tended to have higher birth weight infants than lean fish consumers. Low fish consumption was significantly correlated with low birth weight and small for gestational age (SGA) infants. The more fatty fish that the low fish consumers consumed, the more likely they were to have SGA infants. Fish consumption did not have an impact on the development of gestational diabetes mellitus, macrosomia or pre-term labour-birth. Low fish consumption during pregnancy may be associated with the development of low birth weight and SGA infants in a Turkish population.

Abstract
AIM FK506 (also known Tacrolimus, Prograf) is an immunosuppressant drug which is used to prevent rejection after organ transplantation. Although there are several studies on neuroprotective effect of FK506 on brain ischemia, few reports on effects of FK506 after peripheral nerve ischemia have been reported. In the present study, we examined the size of watershed area after stripping of the epineurial vessels and studied the effect of FK506 on reduction of the size of watershed area. MATERIALS AND METHODS Forty-eight adult female rats were used and randomly divided into four groups as control, sham, FK506-treated and vehicle-treated. In FK506-treated and vehicle-treated groups epineurial vessels around the sciatic nerve (vasa nervorum) were stripped. Additionally, FK506-treated group were received subcutaneous injection of 5 mg/kg FK506. Percent of watershed area (100 × total watershed areas / total nerve area) after stripping and FK506 treatment was calculated. RESULTS We found no significant difference in comparison of the total size of watershed areas in FK506 and vehicle-treated groups or even the percent of the watershed area in both groups. CONCLUSIONS We think that this study will be helpful to understand neuroprotective effect of FK506 and will give an insight into sparing of the nerve fibers from vascular injuries of the peripheral nerve.
