Polyamines (PAs) can improve drought stress tolerance in plants; however, very limited information is available on the mechanism of action of exogenous application by different methods under drought stress in wheat. The present study investigates the mechanism through which seed priming and foliar spraying with PAs protect wheat plants from drought stress. 10 days old wheat seedlings were exposed to drought stress by withholding water alone or with 100 μM PAs solutions (putrescine, Put; spermine, Spm; and mixture of Put and Spm for 10 h seed-priming or three foliar sprays during withholding water...

Urogenital myiasis caused by Psychoda spp. involving human are very rare and present with unusual symptoms. Larvae belonging to Psychoda sp. (Diptera: Psychodidae) were found in the urogenital tract of a 9-year-old girl, who lives in Tajoura, Libya, and had suffered from genital pruritus and moving larvae in urine. This is the first record of such case in Libya.

Metastases to bone are the most frequent cause of destructive lesions to the skeleton in adults . The tumours that are most likely to metastasize to bone are prostate (32%), breast (22%), kidney (16%), lung and thyroid. The typical distribution of metastatic lesions are to the spine, ribs, pelvis, and proximal limb girdles. The humerus is the second most common site for long bone metastases, behind only the femur in its frequency of involvement . It represents the 20% of all bony metastases. We present a clinical case of an 86 yo woman with a previous diagnosis of myofibroblastic sarcoma of the maxillaris who suffers a pathological fracture of the humeral shaft secondary to metastasis and was misdiagnosed and treated for a typical humeral fracture using and intramedullary pinning (Hackethal technique), producing the progression of the disease within the humeral shaft...

Metastatic neoplasms of the thyroid are uncommon when compared to primary tumors of the gland. Renal cell carcinoma (RCC) is a highly aggressive tumor of the urinary system. It can spread all over the body. Isolated solitary metastases of RCC to the thyroid are very rarely observed. A 64-year-old woman with a history of left radical nephrectomy for RCC, was referred to our clinic with palpable thyroid nodule. Ultrasound confirmed the nodule on the left lobe. Histopathological examination of the thyroidectomy specimen revealed that there were two solitary metastasis of RCC...

Thoracic aortic aneurysm with subsequent dissection is a very rare but dangerous complication of Behcet's disease, which is a systemic syndrome that can involve blood vessels of all sizes. Surgical experience in dealing with this complication in patients with Behcet's disease has been limited. We report a 20-year-old patient with Behcet's disease who presented with a giant dissecting thoracic aortic aneurysm. The patient was successfully treated with an aortic root and arch replacement using a frozen elephant trunk technique...

INTRODUCTION: Legg-Calvé-Perthes Disease (LCPD) represents idiopathic avascular necrosis of femoral head in pediatric population. Indications for treatment depend mostly on prognosis about femoral head sphericity and hip congruence at the end of growth. The aim of this review is to highline prognostic factors of LCPD. METHODS: Bibliographic search in PubMed allowed selection of 33 articles concerning prognostic factors and/or classification of LCPD. CONCLUSION: Clinical factors of poor prognosis are overweight, female sex, age exceeding 6 years old, and lack of hip abduction...

Primary lung sarcoma (PLS) is an extremely rare, very aggressive malignancy. Surgical removal is considered the treatment of choice, and patients who have been given conventional radiotherapy have had inferior outcomes. This study is the first describing a case of PLS treated with stereotactic ablative radiotherapy (SABR), which precisely targets a small tumor with a markedly higher biologically effective dose than conventional radiotherapy. The patient was an 82-year-old man who was diagnosed with primary lung leiomyosarcoma based on radiology, pathology, and immunohistochemical examinations...

The incidence of osteoporotic fractures increases with age. Consequently, the global prevalence of osteoporotic fractures will increase with the aging of the population. In old age, osteoporosis is associated with a substantial burden in terms of morbidity and mortality. Nevertheless, osteoporosis in old age continues to be underdiagnosed and undertreated. This may, at least partly, be explained by the fact that evidence of the antifracture efficacy of osteoporosis treatments comes mainly from randomized controlled trials in postmenopausal women with a mean age of 70-75 years...

China's one-child policy (1979-2015) has affected Chinese parenting practices and children's health behaviors and also may have contributed to increased childhood obesity. However, very limited research has investigated the association between one-child policy and childhood obesity. We examined characteristics of single-child families and the influence of one-child policy (indicated by single-child status) on children's weight status and related health behaviors. Data from children aged 6-18years old in the 2011 (n=1580) and 2000 (n=2317) China Health and Nutrition Survey were cross-sectionally analyzed with multilevel models...

PURPOSE: Surgeon-modification of commercially available aortic stent grafts represents a salvage option to treat complex aortic pathologies in high-risk patients. TECHNIQUE: A 68-year old male was referred in our hospital with a contained rupture of the visceral aorta. The patient was previously treated with an infrarenal tube graft 16 years earlier as well as with a Crawford procedure with island patch of the coeliac trunk (TC) and the superior mesenteric artery (SMA) and bypasses to both renal arteries 6 years prior to admission...

OBJECTIVE: Stereotactic body radiotherapy (SBRT) for early-stage non-small-cell lung cancer (NSCLC) is the standard of care in medically inoperable patients. In very elderly patients, previous studies have shown SBRT to offer excellent local control, though with higher toxicities than in younger populations. We report our institutional experience using SBRT in the definitive management of NSCLC in patients ≥80years old. MATERIALS AND METHODS: Using an IRB-approved registry of 158 patients treated with definitive-intent lung SBRT for early-stage NSCLC at our institution between 2010 and 2016, 31 consecutively treated patients ≥80years of age were identified...

BACKGROUND: The incidence of tertiary syphilis involvement in the spinal column with destructive bone lesions is very rare. It is difficult to establish the correct diagnosis from radiographs and histological examination alone. Limited data are available on surgical treatment to tertiary syphilitic spinal lesions. In this article, we report a case of tertiary syphilis in the lumbar spine with osteolytic lesions causing cauda equina compression. CASE PRESENTATION: A 44-year-old man who suffered with low back pain for 6 months and progressive radiating pain at lower extremity for 1 week...

BACKGROUND: Prolonged storage of transfused red blood cells (RBCs) is associated with hemolysis in healthy adults and inflammation in animal models. We aimed to determine whether storage duration affects markers of hemolysis (e.g., serum bilirubin, iron, and non-transferrin-bound iron (NTBI)) and inflammation (e.g., interleukin (IL)-8 and monocyte chemoattractant protein (MCP)-1) in transfused very low birth weight (VLBW) infants. METHODS: Blood samples from 23 independent transfusion events were collected by heel stick before and 2-6 h after transfusion...

The Fe isotopic composition of an individual's whole blood has recently been shown to be an interesting clinical indicator of Fe status. The present study aimed to evaluate the influence of several endemic characteristics of a representative population of the South Kivu province, an Fe-rich volcanic African region, on the whole blood Fe isotopic composition. Both diabetes mellitus and the ferroportin Q248H mutation are very common in Africa and are strongly associated with impairments in Fe metabolism. Fe isotopic analysis of whole blood samples was carried out using multi-collector inductively coupled plasma-mass spectrometry (after chromatographic isolation of the target element)...

A determinant of particular relevance in human development is the socioeconomic status (SES) and, specifically, low SES and poverty. Likewise, family environment is essential in the development of children and a potential mediator or moderator of the effect of broader social conditions. OBJECTIVE: To analyze the role of parenting stress as a mediating variable of the relationship between SES and both externalized and internalized behaviors in preschool children. SUBJECTS AND METHOD: Descriptive secondary base study based on the Longitudinal Survey of Chilean First Infancy that selected a stratified sample, representative by clusters, of 9...

Skull morphology in tapirs is particularly interesting due to the presence of a proboscis with important trophic, sensory and behavioral functions. Several studies have dealt with tapir skull osteology but chiefly in a comparative framework between fossil and recent species of tapirs. Only one study examined an aspect of cranial ontogeny, development of the sagittal crest (Holbrook. J Zool Soc Lond 2002; 256; 215). Our goal is to describe in detail the morphological changes that occur during the postnatal ontogeny of the skull in two representative tapir species, Tapirus terrestris and Tapirus indicus, and to explore possible functional consequences of their developmental trajectories...

Background: Colonic injury represents a rare complication of percutaneous nephrolithotomy (PCNL). Injury of the small bowel is very rare, with only anecdotal case reports in the literature. We report here a rare PCNL complication of jejunal perforation without concomitant colonic injury. Case Presentation: A 45-year-old male underwent PCNL for multiple left kidney stones. At the beginning of the procedure, we faced difficulty in achieving access, but after that the procedure was straightforward and ended smoothly...

Pulmonary arteriovenous malformation (PAVM) is an abnormal blood vessel connecting a pulmonary artery and a vein, and is accompanied by paradoxical embolism to other organs due to a right-to-left shunt. We report the case of a 66-year-old woman with PAVM complicated by splenic infarction and abscess. Although the PAVM had been detected on a chest image 2 years previously, and she had been advised to have further investigations, she decided not to follow this further at the time. She then visited our hospital complaining of worsening dyspnoea on exertion...

Clubfoot is one of the most common congenital orthopaedic anomalies and was described by Hippocrates in the year 400 BC. From manipulation in antiquity to splint and plaster in the Renaissance the treatment had improved before tenotomy. Tenotomy was tested during the 19th century and will be explained in this manuscript; the introduction of subcutaneous tenotomy of the Achilles tendon had focused the attention of surgeons on the surgical treatment of clubfeet. While this operation was very successful in the correction of equinus deformities due to poliomyelitis, cerebral palsy, and old injuries, it was not a panacea for the patient with the congenital clubfoot...
