Biological Evidence Management for DNA Analysis in Cases of Sexual Assault

Alexandros G. SfakianakisστοΝοσολογίαΠριν από 1 ώρα
Biological evidence with forensic interest may be found in several cases of assault, being particularly relevant if sexually related. Sexual assault cases are characterized by low rates of disclosure, reporting, prosecution, and conviction. Biological evidence is sometimes the only way to prove the occurrence of sexual contact and to identify the perpetrator. The major focus of this review is to propose practical approaches and guidelines to help health, forensic, and law enforcement professionals to deal with biological evidence for DNA analysis. Attention should be devoted to av... περισσότερα »

Function analysis of rs9589207 polymorphism in miR-92a in gastric cancer

Alexandros G. SfakianakisστοΟγκολογίαΠριν από 1 ώρα
Abstract MiR-92a was identified as an essential oncogene by promoting the cell proliferation through FBXW7 in gastric cancer (GC). The function of the single nucleotide polymorphism (SNP) located in the mature region of miR-92a (rs9589207) has not been investigated. We found that rs9589207 in miR-92a was involved in the occurrence of GC by acting as a tumor protective factor and was highly associated with tumor size in GC patients instead of tumor number or metastasis in 554 GC patients and 531 cancer-free controls. Besides, the AA genotype in miR-92a could attenuate the promoting... περισσότερα »

Viruses, Vol. 7, Pages 5571-5586: Nucleobase but not Sugar Fidelity is Maintained in the Sabin I RNA-Dependent RNA Polymerase

Αλέξανδρος ΣφακιανάκηςστοMedicine by Alexandros G.SfakianakisΠριν από 1 ώρα
The Sabin I poliovirus live, attenuated vaccine strain encodes for four amino acid changes (i.e., D53N, Y73H, K250E, and T362I) in the RNA-dependent RNA polymerase (RdRp). We have previously shown that the T362I substitution leads to a lower fidelity RdRp, and viruses encoding this variant are attenuated in a mouse model of poliovirus. Given these results, it was surprising that the nucleotide incorporation rate and nucleobase fidelity of the Sabin I RdRp is similar to that of wild-type enzyme, although the Sabin I RdRp is less selective against nucleotides with modified sugar gro... περισσότερα »

Viruses, Vol. 7, Pages 5553-5570: Vector-Enabled Metagenomic (VEM) Surveys Using Whiteflies (Aleyrodidae) Reveal Novel Begomovirus Species in the New and OldWorlds

Αλέξανδρος ΣφακιανάκηςστοMedicine by Alexandros G.SfakianakisΠριν από 1 ώρα
Whitefly-transmitted viruses belonging to the genus Begomovirus (family Geminiviridae) represent a substantial threat to agricultural food production. The rapid evolutionary potential of these single-stranded DNA viruses combined with the polyphagous feeding behavior of their whitefly vector (Bemisia tabaci) can lead to the emergence of damaging viral strains. Therefore, it is crucial to characterize begomoviruses circulating in different regions and crops globally. This study utilized vector-enabled metagenomics (VEM) coupled with high-throughput sequencing to survey begomoviruse... περισσότερα »

Future Internet, Vol. 7, Pages 393-404: Embedding an Identity-Based Short Signature as a Digital Watermark

Αλέξανδρος ΣφακιανάκηςστοMedicine by Alexandros G.SfakianakisΠριν από 2 ώρες
Digital watermarking aims at protecting multimedia content by hiding into it some data that can be used for such purposes as, for example, intellectual property protection or integrity control. Sometimes, the owner of an image would prefer to not transmit, publish, or hand to a cloud service the original image, but rather an encrypted version of it. Encrypted images allow for less embedding room with respect to their unencrypted counterparts, as there is less spatial correlation to leverage upon. An architecture for embedding as payload the digital signature of an encrypted image,... περισσότερα »

Abstract Gastric cancer is difficult to cure because most patients are diagnosed at an advanced disease stage. Systemic chemotherapy remains an important therapy for gastric cancer, but both progression-free survival and disease-free survival associated with various combination regimens are limited because of refractoriness and chemoresistance. Accumulating evidence has revealed that the homomeric α7-nicotinic acetylcholine receptor (A7-nAChR) promotes human gastric cancer by driving cancer cell proliferation, migration, and metastasis. Therefore, A7-nAChR may serve as a potential... περισσότερα »

- Clinical importance of median mandibular flexure in oral rehabilitation: a reviewK. Sivaraman, A. Chopra, S. B. Venkatesh, 2015-10-26 10:25:17 AM Summary The mandible has a property to flex inwards around the mandibular symphysis with change in shape and decrease in mandibular arch width during opening and protrusion of the mandible. The mandibular deformation may range from a few micrometres to more than 1 mm. The movement occurs because of the contraction of lateral pterygoid muscles that pulls mandibular condyles medially and causes a sagittal mov... περισσότερα »

Abstract Background Epidemiological studies have examined the association between human papillomavirus (HPV) and breast cancer, but the findings are inconclusive. This study aimed to detect the prevalence of HPV in breast cancer tissue in patients from northeastern China and define the association between HPV and breast cancer using meta-analysis. Methods Polymerase chain reaction (PCR) was used to test cutaneous or mucosal HPV DNA sequence in 77 breast cancer samples and 77 corresponding adjacent normal tissues. The prevalence of HPV in breast cancer was estimated by pooling dat...περισσότερα »

A new approach for pre-surgical margin assessment of basal cell carcinoma by reflectance confocal microscopy

Alexandros G. SfakianakisστοΑισθητική ΔερματολογίαΠριν από 3 ώρες
Abstract Background Surgical excision represents the elective treatment for BCC. Several non invasive approaches have been proposed for in vivo determination of tumor margin, in order to achieve a radical removal. Objectives We proposed a new approach for lateral margin detection in BCCs through the combination of dermoscopy and Reflectance Confocal Microscopy (RCM). Methods Ten patients with lesions clinically suggestive of non-pigmented BCCs with ill-defined margins were enrolled. All BCCs were first dermoscopically evaluated and the ill-defined margins were marked with a supe...περισσότερα »

Abstract Background Cold atmospheric plasma(CAP) have shown promises for wound healing though little is understood of underpinning mechanisms. Little has been reported so far of their potential treatment of immune-mediated diseases such as psoriasis. Objectives To study CAP-induced cell death and in cytokine release of human keratinocytes as a first assessment of possible CAP use for psoriasis. Methods Using a CAP generator free of energetic ions, we observed its effects on keratinocytes in morphology, cell viability and apoptosis, intracellular and mitochondrial ROS, lysosomal...περισσότερα »

Retrospective study of changes in pharyngeal airway space and position of hyoid bone after mandibular setback surgery by cephalometric analysis

Guidelines for quantification of noise-induced hearing loss in a medicolegal context

Alexandros G. SfakianakisστοNews in OtoRhinoLaryngology - Alexandros G. SfakianakisΠριν από 3 ώρες
Abstract Objectives Guidelines published in 2000 by the authors are widely used by medical and legal professionals in the UK for diagnosis of noise-induced hearing loss (NIHL) in a medicolegal context. However, they cannot be used for quantification of the noise-induced hearing loss, which is required in most cases. This requirement is addressed. Design A method is developed here to quantify NIHL, thereby overcoming this shortcoming. Setting Assessment of NIHL in medicolegal cases. Participants A consecutive series of 124 cases of NIHL is used for evaluation. Main outcome m... περισσότερα »
