Anti-human leukocyte antigen-DPB1 antibody-associated transfusion-related acute lung injury after hematopoietic stem cell infusion.

Although relatively rare among transfusion reactions, transfusion-related acute lung injury (TRALI) is a life-threatening condition, making its prevention, recognition, and early intervention extremely important. Although many etiological factors have been identified, the most common reasons are anti-human leukocyte antigen (anti-HLA) and anti-human neutrophil antigen antibodies that pass from the donor to the recipient during transfusion. TRALI was shown with transfusion of all kinds of blood products, however, it is rarely seen after stem cell infusion.

Stable coexistence or competitive exclusion? Fern endophytes demonstrate rapid turnover favouring a dominant fungus.

Fungal endophytes are critical members of the plant microbiome, but their community dynamics throughout an entire growing season are underexplored. Additionally, most fungal endophyte research has centred on seed-reproducing hosts, while spore-reproducing plants also host endophytes and may be colonized by unique community members. In order to examine annual fungal endophyte community dynamics in a spore-reproducing host, we explored endophytes in a single population of ferns, Polystichum munitum, in the Pacific Northwest.

Retrospective analysis of early- and late-operated meningomyelocele patients.

Purpose: Myelomeningocele (MMC) is one of the commonest congenital malformations. Hydrocephalus develops in 65-85% of cases with MMC. Only 3-10% of MMC patients have normal urinary continence.

Turner Syndrome with Isochromosome Xq.

Short stature and growth retardation in girls commonly occur in patients with Turner syndrome. We present a 19-year-old-girl with primary amenorrhea and growth retardation, who has a mosaic karyotype, 46X,i(Xq)[17]/45,X[8]. Classic Turner syndrome has a more severe phenotype than variant causes of Turner syndrome.

Species-specific effects of passive warming in an Antarctic moss system.

Polar systems are experiencing rapid climate change and the high sensitivity of these Arctic and Antarctic ecosystems make them especially vulnerable to accelerated ecological transformation. In Antarctica, warming results in a mosaic of ice-free terrestrial habitats dominated by a diverse assemblage of cryptogamic plants (i.e.

The Possible Role of XRCC1 Gene Polymorphisms with Idiopathic Non-obstructive Azoospermia in Southeast Turkey.

Purpose: X-ray repair cross-complementing group 1 (XRCC1) plays a role in repairing DNA damage during spermatogenesis. We examined the effects the possible role of two single nucleotide polymorphisms of XRCC1 Arg194Trp and Arg399Gln in DNA repair gene XRCC1 with risk of idiopathic non-obstructive azoospermia (INOA) in a south-east Turkey population.

Materials And Methods: The genotype and allele frequencies of two observed polymorphisms of XRCC1 Arg194Trp and Arg399Gln were examined by polymerase chain reaction-restriction fragment length polymorphism in 102 infertile men with INOA and 102 fertile controls.

Linked homozygous BMPR1B and PDHA2 variants in a consanguineous family with complex digit malformation and male infertility.

In affected members of a consanguineous family, a syndrome, which is concurrence of set of medical signs, is often observed and commonly assumed to have arisen from pleiotropy, i.e., the phenomenon of a single gene variant affecting multiple traits.

Remote Cerebellar Hemorrhage Following Lumboperitoneal Shunt Insertion: A Rare Case Report.

Idiopathic intracranial hypertension is characterized by high intracranial pressure without hydrocephalus or intracranial mass. Surgical treatment includes optic nerve fenestration and insertion of ventriculoperitoneal and lumboperitoneal (LP) shunts. For decreasing intracranial pressure, cerebrospinal fluid (CSF) LP shunt is widely used for the surgical management; it also carries complications such as shunt migration, venous sinus thrombosis, subarachnoid hemorrhage, and subdural and intracerebral hematoma.

Colonization by nitrogen-fixing Frankia bacteria causes short-term increases in herbivore susceptibility in red alder (Alnus rubra) seedlings.

Carbon allocation demands from root-nodulating nitrogen-fixing bacteria (NFB) can modulate the host plant's chemical phenotype, with strong bottom-up effects on herbivores. In contrast to well-studied rhizobia, the effects of other important NFB on plant chemistry and herbivory are much less understood. Here, combining field surveys in the Oregon Coast Range, USA with laboratory experiments, we analyzed how N-fixing Frankia bacteria influenced plant growth, chemistry, and herbivory on Alnus rubra (red alder) seedlings.

Trans-nasal-trans-sphenoidal brain injury by a fencing foil: an unusual case report and brief literature review.

In this report, the authors present an unusual case of a 10-year-old child who suffered a severe headache and rhinorrhea that occurred as a result of fencing foil sports injury via trans-nasal-trans-sphenoidal (TNTS) pathway. Following trauma, the child had shown neurological symptoms such a pupil dilatation, change in consciousness and mild hemiparesia. Imaging demonstrated destruction of bone structures including posterior wall of sphenoid sinus and antero-superior part of sella turcica, and also a contusion at right thalamic region.

Role of alkaline phosphatase intestine-isomerase in acute mesenteric ischemia diagnosis.

Background: The aim of the present study was to investigate the diagnostic value of alkaline phosphatase (ALP) intestine-isomerase, plasma lactate dehydrogenase (LDH), and D-dimer levels in acute mesenteric ischemia.

Methods: Thirty Wistar rats were divided into 5 groups of 6 rats each. In Group 1, blood samples were obtained to determine normal parameter levels.

Ants are less attracted to the extrafloral nectar of plants with symbiotic, nitrogen-fixing rhizobia.

Plants simultaneously maintain mutualistic relationships with different partners that are connected through the same host, but do not interact directly. One or more participating mutualists may alter their host's phenotype, resulting in a shift in the host's ecological interactions with all other mutualists involved. Understanding the functional interplay of mutualists associated with the same host remains an important challenge in biology.

Is cetrimide-chlorhexidine risky for secondary sclerosing cholangitis?

Background: The liver is the most frequent organ for placement of hydatid cyst disease. All known protoscolicidals that are used for echinococcus degeneration have a risk of caustic secondary sclerosing cholangitis. The cetrimide-chlorhexidine combination is an effective protoscolicidal agent for treatment of hydatid liver cysts.

Possible association of FAS and FASLG polymorphisms with the risk of idiopathic azoospermia in southeast Turkey.

To investigate the association of the genetic variants of FAS/FASLG cell death pathway genes in male infertility, we genotyped the FAS -670A/G, -1377G/A, and FASLG -124A/G single-nucleotide polymorphisms (SNPs) by real-time polymerase chain reaction in 108 infertile men with idiopathic azoospermia and in 125 proven fertile controls. The distribution of genotypes and alleles for SNPs at FAS -1377G/A and FASLG -124A/G loci were determined not to be statistically different between the case and control groups. However, the genotype frequencies of SNPs, FAS -670AA and FAS -670AG, were found to be significantly different between the case and control groups.

Truncating mutations in TAF4B and ZMYND15 causing recessive azoospermia.

Background: Azoospermia is the absence of a measurable level of spermatozoa in the semen. It affects approximately 1% of all men, and the genetic basis of the majority of idiopathic cases is unknown. We investigated two unrelated consanguineous families with idiopathic azoospermia.

No association between catalase (CAT) gene polymorphisms and susceptibility to vitiligo in a Turkish population.

Background And Aims: Vitiligo is an acquired hypomelanotic skin disorder resulting from the loss of functional melanocytes from the cutaneous epidermis. Low catalase (CAT) activity and Accumulation of hydrogen peroxide (H2O2) have been demonstrated in the epidermis of vitiligo patients. Some polymorphisms on catalase gene may have effect on the quantity and activity of catalase enzyme.

Chromosome heteromorphisms are more frequent in couples with recurrent abortions.

Chromosomal heteromorphism is considered a variant of a normal karyotype, but it is more frequent in couples with repeated miscarriages. We investigated chromosomal heteromorphism in couples with repeated miscarriages in comparison with a control group. A total of 455 couples who applied to our genetic diagnosis laboratory in Diyarbakir, Turkey, were evaluated for chromosome heteromorphisms; 221 of these couples (the study group) had recurrent abortions and 234 of them (the control group) had no history of abortions and had at least one living child.
