Accurate skeletal analysis is needed in order to properly identify skeletal remains. Cases of misidentification occur all over the United States and may be avoided with an understanding of observer error and the appropriate level of training. In this study, four novice observers with limited osteological training conducted osteological analyses on three different skeletal remains to assess intraobserver and interobserver reliability

Onion is a high-value vegetable consumed in Nigeria on a daily basis, and it forms an integral part of the diet, but the nutritional quality is low due to lack of appropriate cultural practices. The study examined the effects of planting dates on the nutritional quality of onion varieties in Ogbomoso, Nigeria. Five onion varieties (Local white, a local red, karibou, gandiol+, and safari) were subjected into four different planting dates namely, two under rain-fed (early April and August) and two under irrigation (early September and November).

Intra-oral radiography is ubiquitous in dentistry and practitioners are increasingly using extra-oral radiography in everyday practice. Practitioners may encounter findings on radiographs that they are unfamiliar with and are unsure of the clinical significance. This retrospective study aimed to ascertain the radiographic presentations which were more likely to prompt these clinicians to seek an opinion from a Dento-maxillofacial radiologist (DMFR) and the most common pathologies referred.

A kind of alcohol-soluble phosphate adhesive was prepared by using phosphate solution as raw material. A hybrid high temperature and high strength adhesive was prepared by adding phenolic resin. The wetting condition of water-soluble and alcohol-soluble phosphate adhesive on the surface of hydrophobic material, the composition and mechanical properties of the adhesive were analyzed by means of liquid drop shape analyzer (DSA), X-ray diffraction instrument and universal tensile force machine. The results show that the alcohol-soluble phosphate adhesive has good wetting effect on hydrophobic materials and has excellent high temperature resistance and mechanical properties.

This study investigates proximate composition and characterization of Moringa oleifera seed-oil using four methods of extraction (Cold pressing (CP), Enzyme assisted cold pressing (EACP), Enzyme assisted aqueous extraction (EAAE) and solvent extraction (SE)) and compared with olive oil. The results of proximate analysis of the kernel reveals (7.20 moisture content, 43.12 protein, 33.16 fat, 3.51 Ash, and 6.81 Carbohydrate by difference) %, while the oil yield obtained for CP, EACP, EAAE and SE were (7.75, 12.08, 23.25 and 33.16)%. The fatty acids composition and bioactive compounds were determined through GC-MS analysis. Melting and crystallization temperature ranges: -15.86 to 3.21 and 8.30 to -13.63 °C, respectively. There is a significant difference in term of oil yield, with cold pressing method having the lowest oil yield of 7.8 %. However, the quality of CP extracted Moringa oleifera oil was compared with virgin olive oil; it revealed its potentials as a good source of oleic acid making it to be a good substitute for virgin olive oil.

The study seeks to investigate the casual effect of the efficient energy use and GDP (economic growth) on fossil fuel consumption (Nonrenewable) for the sub Saharan Africa for the period 1980 to 2014. The study also seeks to investigate solutions to environmental issues. Zivot-Andrews unit root test with a structural break, Phillips and Perron unit root test with structural break revealed that the investigated variables become stationary at first-differences. The Gregory-Hansen cointegration test with a structural break shows efficient energy use, economic growth and energy consumption are co-integrated. The long-run estimates obtained from the VECM model indicate that in account of the changes in the structure of the economies, the environmental Kuznets curve does not exist due to validity of a U shaped curve. An increase in output growth (GDP) and efficient energy use positively affect environmental pollution. Based on the findings of this study, the study recommends investment in green technology as the economy growths.

We aimed to determine whether the excision repair cross-complementation group 1 (ERCC1) expression predicts response to cisplatin-based chemotherapy in patients with small cell lung cancer (SCLC). This was a retrospective study, in which hospital files of 31 patients (29 males, 2 females; mean age, 62.26±7.71 years) were reviewed. All patients were treated with etoposide+cisplatin. The lung biopsy and mediastinal lymph node samples were applied anti-human monoclonal antibodies against ERCC1: immunohistochemical staining was considered positive if 25-100% of the cells showed nuclear staining, and negative if less than 25% of the cells showed negative or slight staining. Response to treatment was evaluated as regression (complete or partial response), progressive disease, or stable disease. Of the patients, 18 (58.1%) had limited-stage, and 13 (41.9%) had extensive-stage SCLC. Median follow-up duration was 15 months (range: 1-60 months). ERCC1 staining was positive in 9 of 31 patients (29.0%). In 12 patients (38.7%), tumor regression (complete or partial response) was obtained after chemotherapy. Tumor regression rate was higher in ERCC1 positive patients than those with negative ERCC1 expression (66.7% vs. 27.3%, p=0.036). In conclusion, high expression of ERCC1 was associated with higher response rate to cisplatin-based regimens in patients with SCLC.

Squamous cell carcinoma of the external auditory canal may masquerade as an infective process causing late diagnosis. A delay in treatment as a result of missed diagnosis would carry a poor prognosis as the disease progresses to an advanced stage. We present a case of a man with history of chronic otorrhea, who developed left sided otalgia associated with hearing loss. otoscopic examination shows a mass in her left ear and pus discharge which was initially treated as an infection. The biopsy of the mass was proven to be squamous cell carcinoma. High index of suspicion is necessary when encountering patients presenting with a mass in the ear canal with prior history of chronic otorrhea or cholesteatoma. Proper tissue biopsy is crucial. Early diagnosis is required for better prognosis for the patient.

Sanfilippo syndrome, a type of mucopolysaccharidosis (MPS), is an autosomal recessive lysosomal storage disease. The disorder is characterized by bone abnormalities (i.e. abnormally long arms and legs when compared with the trunk length), as well as abnormal bone shapes and skin thickening.In general, patients with Sanfilippo syndrome have sharp and coarse facial features, thickening of the lips and enlargement of the mouth and tongue. Hypoplasia of hard dental tissue is also present. The parents of a 5-year-old female patient were referred to Konya Oral and Dental Health Hospital because of tooth pain. A full dental examination could not be conducted because the patient was not cooperative. Thus, we decided to perform the patient’s treatment under general anaesthesia. As the patient had a history of difficult intubation and the planned dental procedures could be completed in a short time, under sedoanalgesia.

The application of electronic-nose (E-nose) technologies in forensic science is a recent new development following a long history of progress in the development of diverse applications in the related biomedical and pharmaceutical fields. Data from forensic analyses must satisfy the needs and requirements of both the scientific and legal communities. The type of data collected from electronic-nose devices provides a means of identifying specific types of information about the chemical nature of evidentiary objects and samples under investigation using aroma signature profiles of complex gaseous mixtures containing volatile organic compounds (VOCs) released from manufactured products and parts of the human body. E-nose analyses also provide useful qualitative information about the physicochemical characteristics and metabolic conditions of human subjects without the need for time-consuming analyses to identify all chemical components in human-derived volatile mixtures.
