Background:
Hepatocellular carcinoma (HCC) ranks as 5th most common cancer. Chronic infection by hepatitis viruses especially HBV and HCV lead to complicated microenvironment which may lead to hepatocarcinogenesis. Lnc RNAs and serum Amyloid A (SAA) have been suggested to have role in tumorogenesis and progression. In this work we investigated the role of lnc RNA AF085935 and SAA as a diagnostic biomarkers in sera of HBV, HCV, HCC patients.
Subjects and Methods: RT-PCR technique was used to assess Lnc RNA AF085935 quantitative expression and ELISA technique was used to detect expression level of SAA at sera of 149 adult Egyptian subjects. They were divided as 35 HCC patients on top of HCV and 24 HCC patients on top of HBV, 35 patients with HBV and 35 patients with HCV and 20 healthy donors.
Results: The level of LncRNA-AF085935 and SAA were high significantly upregulated in HCC patients, HCV patients and HBV patients compared with that in normal controls (p value = <0.001). In addition, higher expressions of Lnc RNA-AF085935 and SAA were observed in HCC patients than in HCV and HBV patients. SAA showed a relatively high accuracy for HCC screening (area under the curve (AUC) = 0.927, 95 % confidence interval (CI) = 0.858-0.997) to be differentiated from normal control. LncRNA-AF085935 showed a relatively higher accuracy for HCC screening ( AUC= 0.931, 95 % CI  = 0.862-1.00) than SAA (AUC = 0.74, 95 % CI = 0.587-0.894) from HBV patients.
Conclusion: Lnc RNA-AF085935 and SAA were observed with an aberrant serum level in sera of HCC, HCV and HBV patients. Lnc RNA-AF085935 and/or SAA can be used as potential biomarkers in HCC tumorogenesis.

BACKGROUND: Hair transplantation is the only method available to regrow new hairs; hence, enhancing the results of this procedure using state-of-the-art methods has become mandatory in clinical practice. Recent studies have suggested that significant improvements in hair density and stimulation of hair growth occur when follicular units are pretreated with platelet plasma growth factors before implantation. This study aimed to investigate and compare the outcomes of this procedure using platelet-rich plasma (PRP)-preserved hair grafts and saline-preserved hair grafts.

METHODS: This is a randomized controlled study. The study included 27 men and 3 women aged 22-51 years. Clinical examination (general and local) and preoperative marking were performed in these patients. The surgical technique involved graft extraction, PRP preparation, and hair implantation. Postsurgical patient satisfaction and clinical improvement were evaluated.

RESULTS: There were significant differences between the groups in hair uptake and hair thickness after 1 year follow-up, with value <0.05. Using PRP therapy with follicular unit extraction increases the success of follicular unit extraction hair transplantation. All participants in the PRP group had >75% hair regrowth after 6 months. They had more rapid improvements in hair density and skin recovery than those in the non-PRP group.

CONCLUSION: Preserving hair grafts in PRP before implantation increases the hair density, the graft uptake, and the hair thickness compared with pretreatment preservation of hair grafts in saline.

BACKGROUND: Although a boxy breast is a common aesthetic problem following breast reduction and mastopexy, literature regarding this deformity is scarce. It is vaguely described as a definitive postreduction deformity. To address this complication, it is important to fully analyze the problem, understand and predict its causes, and then try to prevent it.

METHODS: This study included two groups. Group 1 included 14 patients presenting with boxy postoperative breasts. Revision surgeries were conducted for all patients, and the first algorithm was created for quantifying breast surgery in revision cases. Group 2 included 37 cases of primary mammaplasty reduction/mastopexy performed between 2016 and 2019. All the patients in this group were treated as per the study algorithm.

RESULTS: Patient satisfaction was measured on a scale of one to 10, with one being extremely dissatisfied and 10 being extremely satisfied. The results indicated overall satisfaction, with average scores of 9.5 and 9.1 in groups 1 and 2, respectively; the scores of surgeon satisfaction were 8.2 and 8.6, respectively.

CONCLUSIONS: The proposed algorithm, preoperative markings, intraoperative techniques, and postoperative orientation may help achieve optimal results and prevent undesired deformities or asymmetry. Applying a flexible and simplified algorithm provided a more objective plan, which enabled surgeons to attain more satisfactory results. Following a preset quantified plan supported and shortened learning curves and objectively addressed the common postoperative complication, breast boxing.

We performed a retrospective study comparing 2 patient groups. Each cohort included 22 cases of skin cancer of the external ear. Each patient required resection of the affected part of the external ear, followed by flap reconstruction.

METHODS: The patients in Cohort A underwent external ear reconstruction with a classic Antia-Buch flap, as described by Antia and Buch in 1967: The defect was closed by mobilizing an advancement flap from the root of the helix (upper ear), which was closed in a V-Y fashion, after a rim of healthy scaphal cartilage was resected to allow approximation of the skin. The patients in Cohort B underwent external ear reconstruction with a modified Antia-Buch flap, as presented by Franssen and Frechner in 2010. Here, a wedge of skin was removed from the ear lobe (lower ear), to allow mobilization of an advancement flap from the caudal end of the ear, to close the defect.

RESULTS: Both techniques allowed tension-free closure. Cohort B, however, required less dissection of the ear. The entire cephalic ear remained unaffected and no scaphal cartilage was sacrificed, thus preserving ear width, with scars that were overall less visible. Also, the loss in ear height associated with Cohort B was easily symmetrized by contralateral ear lobe reduction.

CONCLUSIONS: Cohort B achieved closure with less ear dissection, achieving excellent morphological outcomes. The patients in Cohort B had superior levels of satisfaction with scars and ear symmetry than those in Cohort A.

Kader, A. - E. F. H., G. Said, M. M. El-Naggar, and B. A. Anees, "Characterization and electrical properties of methyl-2-hydroxyethyl cellulose doped with erbiumnitrate salt", Journal of applied polymer science, vol. 102, issue 3, pp. 2352-2361, 2006. Abstract

X-ray diffraction, infrared (IR), and electrical properties for pure and Er (NO3)3-doped methyl-2-hydroxyethyl cellulose (MHEC) with concentrations of 0.5, 1, 2, 5, 7, and 10 wt % were studied. X-ray analysis indicates that the addition of Er (NO3)3, which is a crystalline material, to MHEC at concentrations 10 and 13 wt % leads to the formation of crystalline phases in the amorphous polymeric matrix. The appearance of the bending mode ν2 and the combination mode (ν1 + ν4) of Er (NO3)3 in the IR spectra of composite samples indicates the coordination of nitro group in the chains of MHEC. From the I–V characteristics, it was found that the charge transport mechanism in MHEC appears to be essentially space charge limited conduction, while the predominant mechanism in the composite samples is Poole–Frenkel. Values of both drift mobility (μ) and the charge carrier density (n) has been reported. The temperature dependence conductivity data has been analyzed in terms of the Arrhenius and Mott's variable range hopping models. Different Mott's parameters such as the density of states, N(EF), hopping distance (R), and average hopping energy (W) have been evaluated.
