INTRODUCTION: Cervical spine is part of the spine with the most mobility in the sagittal plane. It is important for surgeons to have reliable, simple and reproducible parameters to analyse the cervical. MATERIAL AND METHOD: This study is a systematic review and a critique of current parameters to help improve the study of cervical spinal balance. We conducted a systematic search of PUBMED/MEDLINE for literature published since January 2014. Only studies written in English and containing abstracts were considered for inclusion...

Stature estimation is an important step to create a biological profile for human identification of unknown individuals in forensic anthropological practice, and it is well known that the long bone length is highly correlated with this feature. The purpose of the present study is to develop formulae for height estimation, based on simple linear regression model for humerus, femur and tibia in Mexican contemporary population. Stature was taken in 56 males and 30 female corpses as well as maximum length of three long bones of the limbs after autopsy following the Menéndez et al...

Mastitis is a disease of major economic importance to the dairy cattle sector because of the high incidence of clinical mastitis and prevalence of subclinical mastitis and, consequently, the costs associated with treatment, production losses, and reduced animal welfare. Disease-recording systems compiling data from a large number of farms are still not widely implemented around the world; thus, selection for mastitis resistance is often based on genetically correlated indicator traits such as somatic cell count (SCC), udder depth, and fore udder attachment...

In vivo calcium (Ca2+) imaging using two-photon microscopy allows activity to be monitored simultaneously from hundreds of individual neurons within a local population. While this allows us to gain important insights into how cortical neurons represent sensory information, factors such as photo-bleaching of the Ca2+ indicator limit imaging duration (and thus the numbers of stimuli that can be tested), which in turn hampers the full characterization of neuronal response properties. Here, we demonstrate that using an encoding model combined with presentation of natural movies results in detailed characterization of receptive field (RF) properties despite the relatively short time for data collection...

Herein a label-free immunosensor based on electrolyte-gated organic field-effect transistor (EGOFET) was developed for the detection of procalcitonin (PCT), a sepsis marker. Antibodies specific to PCT were immobilized on the poly-3-hexylthiophene (P3HT) organic semiconductor surface through direct physical adsorption followed by a post-treatment with bovine serum albumin (BSA) which served as the blocking agent to prevent non-specific adsorption. Antibodies together with BSA (forming the whole biorecognition layer) served to selectively capture the procalcitonin target analyte...

Aberrations in eating patterns constitute a substantial public health burden. Computer-based paradigms that measure responses to images of foods are potentially useful tools for assessing food attitudes and characteristics of eating behavior. In particular, food choice tasks attempt to directly probe aspects of individuals' decisions about what to eat. In the Food Choice Task participants rate the healthiness and tastiness of a variety of food items presented one at a time. Next, participants choose for each food item whether they prefer to eat the item vs...

Human papilloma virus (HPV) is a known cause of cervical cancer, squamous cell carcinoma and laryngeal cancer. Although treatments exist for HPV-associated malignancies, patients unresponsive to these therapies have a poor prognosis. Recent findings from vaccine studies suggest that T-cell immunity is essential for disease control. Because Epstein-Barr Virus (EBV)-specific T cells have been highly successful in treating or preventing EBV-associated tumors, we hypothesized that the development of a manufacturing platform for HPV-specific T cells from healthy donors could be used in a third-party setting to treat patients with high-risk/relapsed HPV-associated cancers...

Background Despite the need to curb the menace resulting from the negative trajectory of disruptive behaviour disorders (DBD) in societies of the world today, there is yet a dearth of locally standardised tools for the early detection of these disorders in Nigeria. This study was aimed at standardising the DBD teacher rating scale (DBD-TRS) to be culturally specific using teachers' ratings of their students. Objectives To establish norm scores for the three categories of DBD on the DBD-TRS, to evaluate the reliability, validity, predictive power, sensitivity and specificity of DBD-TRS items for identifying DBD symptoms amongst children/adolescents between the ages of 4 and 16 years...

Many studies have shown that randomized clinical trial with long-term follow-up found no improvement in stage II esophageal carcinoma (EC) patients receiving preoperative neoadjuvant chemoradiotherapy or chemotherapy treatment, this limitation underscored the urgent need for novel and reliable biomarkers for prognosis and prediction in stage II EC. miR-21 is frequently over-expressed while programmed cell death 4 (PDCD4) is often down-regulated in solid tumors. This study aimed to investigate the clinicopathological and prognostic significance of miR-21 and PDCD4 expression and to elucidate any correlation between miR-21 and PDCD4 expression in stage II EC patients...

Subsolid pulmonary nodules are commonly encountered in lung cancer screening and clinical routine. Compared to other nodule types, subsolid nodules are associated with a higher malignancy probability for which the size and mass of the nodule and solid core are important indicators. However, reliably measuring these characteristics on computed tomography (CT) can be hampered by the presence of vessels encompassed by the nodule, since vessels have similar CT attenuation as solid cores. This can affect treatment decisions and patient management...

Pichia pastoris (syn. Komagataella phaffii) is one of the most common eukaryotic expression systems for heterologous protein production. Expression cassettes are typically integrated in the genome to obtain stable expression strains. In contrast to Saccharomyces cerevisiae, where short overhangs are sufficient to target highly specific integration, long overhangs are more efficient in P. pastoris and ectopic integration of foreign DNA can occur. Here, we aimed to elucidate the influence of ectopic integration by high throughput screening of >700 transformants and whole genome sequencing of 27 transformants...

Porcine epidemic diarrhea (PED), which is caused by porcine epidemic diarrhea virus (PEDV), is an acute, highly contagious enteric disease characterized by severe watery diarrhea, vomiting, dehydration, and high mortality in suckling piglets. A real-time reverse-transcription recombinase polymerase amplification assay (RT-RPA) was developed based on the nucleocapsid gene of PEDV. RT-RPA assay was performed at 40 °C for 20 min. The assay could detect both the classical and variant PEDV strains, and there was no cross-reaction with other pathogens tested...

This study investigated the thermal degradation of a veterinary drug, chloramphenicol, in model solutions (water), as well as in spiked and incurred mussel tissues to understand its fate in the food supply chain. Thermal degradation kinetics followed a first-order model in water (e.g. degradation rate: 0.0018-0.0025 min-1 at 100 °C). After 1 h at 100 °C, the percentage degradation in spiked tissues (28.1 ± 7.1%) was significantly different (p < .05) from the values in water (14.2 ± 1...

Various stability indicating techniques find application in the early stage development of novel therapeutic protein candidates. Some of these techniques are used to select formulation conditions that provide high protein physical stability. Such approach is highly dependent on the reliability of the stability indicating technique used. In this work, we present a formulation case study where we evaluate the ability of differential scanning fluorimetry (DSF) and isothermal chemical denaturation (ICD) to predict the physical stability of a model monoclonal antibody during accelerated stability studies...
