Abstract
Hair luster is a key attribute of healthy hair and a crucial aspect of cosmetic appeal, reflecting the overall health and vitality of hair. Despite its significance, the advancement of therapeutic strategies for hair luster enhancement have been limited due to the absence of an effective experimental model. This study aimed to establish a novel animal model to assess hair gloss, employing ultraviolet (UV) irradiation on C57BL/6 mice. Specifically, UVB irradiation was meticulously applied to the shaved skin of these mice, simulating conditions that typically lead to hair luster loss in humans. The regrowth and characteristics of the hair were evaluated using a dual approach: an Investigator's Global Assessment (IGA) scale for subjective assessment and an image-based pixel-count method for objective quantification. These methods provided a comprehensive understanding of the changes in hair quality post-irradiation. To explore the potential reversibility of hair luster changes, oral minoxidil was administered, a treatment known for its effects on hair growth and texture. Further, to gain insights into the underlying biological mechanisms, bulk RNA transcriptomic analysis of skin tissue was conducted. This analysis revealed significant alterations in the expression of keratin-associated protein (KRTAP) genes, suggesting modifications in hair keratin crosslinking due to UV exposure. These changes are crucial in understanding the molecular dynamics affecting hair luster. The development of this new mouse model is a significant advancement in hair care research. It not only facilitates the evaluation of hair luster in a controlled setting but also opens avenues for the research and development of innovative therapeutic strategies. This model holds promise for the formulation of more effective hair care products and treatments, potentially revolutionizing the approach towards managing and enhancing hair luster.

Abstract
PURPOSE Photobiomodulation (PBM), encompassing low-energy laser treatment and light-emitting diode (LED) phototherapy, has demonstrated positive impacts on skin rejuvenation and wound healing. Organic light-emitting diodes (OLEDs) present a promising advancement as wearable light sources for PBM. However, the biological and biochemical substantiation of their skin rejuvenation and wound healing effects remains limited. This study aimed to ascertain the safety and efficacy of OLEDs as a next-generation PBM modality through comprehensive in vitro and in vivo investigations. MATERIALS AND METHODS Cell viability assays and human ex vivo skin analyses were performed after exposure to OLED and LED irradiation to examine their safety. Subsequent evaluations examined expression levels and wound healing effects in human dermal fibroblasts (HDFs) using quantitative reverse transcription-polymerase chain reaction, enzyme-linked immunosorbent assay, and wound healing assays post-irradiation. Additionally, an in vivo study was conducted using a ultra violet (UV)-irradiated animal skin model to explore the impact of OLED exposure on dermal collagen density and wrinkles, employing skin replica and tissue staining techniques. RESULTS OLED irradiation had no significant morphological effects on human skin tissue, but caused a considerably higher expression of collagen than the control and LED-treated groups. Moreover, OLED irradiation reduced the expression levels of matrix metalloproteinases (MMPs) more effectively than did LED on HDFs. OLED irradiation group in HDFs had significantly higher expression levels of growth factors compared to the control group, but similar to those in the LED irradiation group. In addition, OLED irradiation on photo-aged animal skin model resulted in increased collagen fiber density in the dermis while reducing ultra violet radiation-mediated skin wrinkles and roughness, as shown in the skin replica. CONCLUSION This study established comparable effectiveness between OLED and LED irradiation in upregulating collagen and growth factor expression levels while downregulating MMP levels in vitro. In the UV-irradiated animal skin model, OLED exposure post UV radiation correlated with reduced skin wrinkles and augmented dermal collagen density. Accelerated wound recovery and demonstrated safety further underscore OLEDs' potential as a future PBM modality alongside LEDs, offering promise in the realms of skin rejuvenation and wound healing.

Abstract
BACKGROUND Oral collagen peptides supplementation was reported to improve skin integrity and counteract skin aging. AIMS A randomized, double-blinded, placebo-controlled study was conducted to clinically evaluate the impact of low-molecular-weight collagen peptides on the human skin. PATIENTS/METHODS Healthy adult participants (n = 100) were randomly assigned to receive a test product containing low-molecular-weight collagen peptides or a placebo. Parameters of skin wrinkles, elasticity, hydration, and whitening (melanin and erythema indexes) were measured at baseline and after 4, 8, and 12 weeks. RESULTS Compared with the placebo group, the average skin roughness, maximum of all peak-to-valley values, maximum peak height of the wrinkle, and average maximum height of the wrinkle were significantly improved in the test group. Parameters of skin elasticity, including overall elasticity, net elasticity, and biological elasticity, were also significantly improved in the test group at Week 12 as compared with the placebo group. Moreover, skin hydration and whitening parameters changed more significantly in the test group than in the placebo group. None of the participants experienced adverse events related to the test product. CONCLUSIONS Taken together, these findings suggest that low-molecular-weight collagen peptides supplementation can safely ehance human skin wrinkling, hydration, elasticity, and whitening properties.

Abstract
Alongside increases in the average lifespan and a growing interest in anti-aging remedies, the demand for at-home skincare devices is rapidly expanding in the cosmetic market. This study aimed to assess the safety and efficacy of a novel home-use handheld multi-energy-based device for skin rejuvenation that simultaneously emits low level light, low-dose radiofrequency, low-energy microcurrent, and low-intensity ultrasonic wave. This prospective, randomized, split-face clinical trial enrolled 36 healthy Korean women. After 8 weeks of device use, parameters associated with skin aging were assessed. Additionally, a preliminary ex vivo study and skin biopsy following device use were performed to confirm safety and efficiency of the device. Parameters associated with skin aging including skin hydration, elasticity, roughness, skin pore size, and eye wrinkle volume showed significant improvements after 8 weeks of the device use, relative to baseline measurements and the control side. No adverse effects were observed during the follow-up period. Results of ex vivo and in vivo skin tissue studies correlated with clinical findings, which showed an increase in the expression of type 1 collagen and a decrease in the expression of matrix metalloproteinase-1, which is related to the skin aging phenotype. The expression of loricrin and involucrin, major components of the epidermal skin barrier, also increased after the use of the device. Multi-energy-based device is effective for skin rejuvenation and tolerable, without any considerable adverse effects.

Abstract
BACKGROUND Recent research suggests that persimmon leaf extract (PLE) has an effect on inflammatory skin diseases. Previously, PLE is revealed to inhibit not only nitric oxide production but also inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) expression levels in mouse macrophages in vitro. Moreover, it significantly reduced IL-6 production and 5α-reductase expression in human follicle dermal papilla cells (HFDPCs). This study aimed to determine whether the PLE-containing BLH308 complex improves hair growth in clinical trials. MATERIALS AND METHODS A total of 88 participants were recruited, and were instructed to orally take BLH308 or the placebo twice a day for 24 weeks. The mean age of the test group was 38.52 ± 7.98 years and that of placebo group was 38.98 ± 8.80 years. The study was conducted for 24 weeks, and hair density, thickness, and gloss were evaluated. All participants completed a satisfaction survey questionnaire. RESULTS The test group showed significantly increased hair density and hair diameter at week 24 compared with the placebo group (p = 0.0015 and p = 0.0001, respectively). Although not statistically significant, the degree of gloss also showed higher improvement in the test group compared to the placebo group. CONCLUSIONS Our data demonstrated that oral consumption of the BLH308 complex containing PLE significantly increased hair density and thickness compared to the placebo group, showing its possible role in promoting hair growth.

Abstract
BACKGROUND Age-related changes in scalp parameters affect hair quality and scalp condition. However, detailed data on biophysical parameters of the scalp across age groups remain scarce. We aimed to investigate the differences in scalp parameters between individuals in their 20s and 50s and analyze their sex-specific variations. MATERIALS AND METHODS Two hundred participants (160 women and 40 men) were equally divided into 20s and 50s age groups. Biophysical parameters of the scalp, including elasticity, pH, trans-epidermal water loss (TEWL), sebum production, desquamation, firmness, redness, and yellowness, were measured in the vertex, occipital, and temporal regions. Hair density and thickness were measured in the temporal region. The accumulation of advanced glycation end products (AGEs) in the skin was noninvasively measured in a subset of 60 women. RESULTS Skin firmness and redness increased with age in women, whereas yellowness increased with age in both sexes. Sebum production and pH levels were significantly lower in the 50s age group than in the 20s age group, particularly in women. TEWL was lower in men in their 50s than in those in their 20s, particularly in the occipital region. A significant reduction in hair density was observed in the 50s age group in both sexes. AGE accumulation in the skin increased with age and was correlated with scalp skin yellowness. CONCLUSION Age-related changes in scalp parameters have important implications for hair health and scalp condition. These findings emphasize the importance of considering age and sex when developing hair care strategies.

Abstract
Matrix metalloproteinase-1 (MMP-1) is a zinc-containing endopeptidase that degrades dermal collagen and other extracellular matrix molecules. It is recognized as one of the most important indicators of cellular senescence and age-related skin changes. Here, we introduced a novel MMP-1 peptide nucleic acid (PNA) derivative-PNA-20 carboxyethyl fluorene (CEF)-which can interact with and consequently silence the MMP-1 gene sequence. The investigation on the efficacy of PNA-20 CEF in MMP-1 silencing in human dermal fibroblasts revealed significantly decreased expression of MMP-1 at both gene and protein levels. Treatment with PNA-20 CEF showed significantly increased expression of collagen I protein, indicating its potential role in preventing the degradation of collagen I and consequently combating the skin aging process. Its topical application on 3D human skin tissue showed successful absorption into the epidermis and the upper dermis. Furthermore, the additional 4-week single-arm prospective study on 21 Asian women revealed improvements in facial wrinkles, skin moisture, elasticity, and density after the use of the topical PNA-20 CEF cosmeceutical formulation. Additional in-vitro and ex-vivo studies are needed for a comprehensive understanding of the skin anti-aging effects of MMP-1 PNA.

Abstract
The glycation process has been recognized as one of the critical parameters that accelerate signs of skin aging, especially in skin exposed to environment factors, such as ultraviolet radiation. Although previous studies showed the anti-inflammatory and antiaging properties of the hydrolyzed collagen tripeptide (CTP), its exact mechanism is not fully understood. Therefore, in this study, we sought to investigate the effect of a topical CTP on facial skin. Our group designed a 4 week prospective, single-arm study of 22 Asian women who applied topical CTP. We observed significant improvements in skin wrinkles, elasticity, and density with a reduction in skin accumulation of advanced glycated end products (AGEs) at week 4 without any adverse effects. The in vitro study revealed a preventive effect of the topical CTP on the accumulation of AGEs, denatured collagen production, and reactive oxygen species in dermal fibroblasts. Moreover, treatment with the CTP decreased induction of matrix metalloproteinases while increasing the collagen 1 level. These results suggest that the application of a topical CTP might improve clinical aging phenotypes via the inhibition of glycation and oxidative stress, leading to a delay in cellular aging.

Abstract
Dry and eczema-prone skin conditions such as atopic dermatitis and xerotic eczema primarily indicate an impaired skin barrier function, which leads to chronic pruritus. Here, we investigated the effects of a novel emollient containing H.ECMTM liposome, which contains a soluble proteoglycan in combination with hydrolyzed collagen and hyaluronic acid. A prospective, single-arm study was conducted on 25 participants with mild atopic dermatitis or dry skin to assess the hydration and anti-inflammatory effect of the novel emollient applied daily over four weeks. All efficacy parameters, including itching severity, transepidermal water loss, and skin hydration, improved significantly after four weeks. The in vitro and ex vivo studies confirmed the restoration of the skin’s barrier function. The study revealed the clinical and laboratory efficacy of H.ECMTM liposome in reducing itching and improving the skin’s barrier integrity. Thus, the use of H.ECMTM liposome can be considered a therapeutic option for dry and eczema-prone skin.

Abstract
BACKGROUND As the average life expectancy increases, skin aging and wrinkles due to photoaging have gained attention. Collagen is closely involved in the process of skin aging. Among the potential methods of drug delivery to the skin, oral disintegrating films show promise for their ability to bypass the loss of active components that is typical of drug absorption via oral administration. This study was conducted to investigate the effect of an oral disintegrating collagen film on skin aging. METHODS We performed a prospective, single-arm study in a cohort of 22 women to assess the anti-aging effect of a novel oral disintegrating film containing collagen applied daily over a 12-week period. We measured the clinical indicators of skin integrity and performed immunofluorescence and high-performance liquid chromatography analyses of an ex vivo oral mucosa model to compare the absorption rates of collagen films and conventional oral tablets via the mucosa. RESULTS We found that the oral disintegrating collagen film reduced skin wrinkle depth and number and significantly increased skin elasticity and density. CONCLUSIONS The novel mode of delivery of collagen via oral disintegrating films has a clinically potential anti-aging efficacy and is safe and convenient for daily use.

Abstract
Hair greying depends on the altered presence and functionality of hair follicle melanocytes. Melanocyte stem cells (MelSCs) reside in the bulge of hair follicles and give rise to migrating and differentiating progeny during the anagen phase. Ageing, genotoxic stress, redox stress and multiple behaviour-associated acute stressors have been seen to induce hair greying by depleting the MelSC pool, a phenomenon which is accompanied by ectopic pigmentation of these cells, followed by their depletion from the stem cell niche. This aberrant differentiation produces a state from which a return to stem cell-like quiescence appears to be lost. The cellular features of stress-induced hair greying have been extensively studied in murine models. Here, we describe a method to assess and quantify human hair follicle MelSC differentiation by measuring ectopically pigmented MelSCs in isolated human hair follicles exposed to specific stress signal mediators. Ionizing radiation, hydrogen peroxide and noradrenaline have been shown to cause hair greying in mice. We demonstrate here that isolated, ex vivo cultured human hair follicles exposed to these treatments display similar ectopic pigmentation within the bulge area which is accompanied by induction of differentiated melanocytic markers. This study suggests that as in murine models, stress signalling induces closely matching phenotypic changes in human hair follicles which can be monitored and studied as a surrogate model for early steps in human hair greying.

Abstract
PURPOSE Incisional hernia is the most common complication of laparotomy. Postoperative parietal defects tend to relapse, even after the most optimal surgical methods. The aim of this study was to present the effectiveness of an adapted retromuscular technique with prolene mesh and a hernial sac, in patients with large incisional median hernias. The reported results were obtained by our team after more than 15 years of experience. METHODS This retrospective study included 139 consecutive cases of large median incisional hernias operated on using a retromuscular mesh and hernial sac technique. The cross-sectional diameter of incisional hernias was larger than 10 cm, being classified in the W3 group, according to the European Hernia Society classification. RESULTS The study included 83 females (59.71%) and 56 males (40.29%) with a median age of 62.4 ± 16.6 years and an average body mass index of 32.4 ± 7.6 kg. The hernia was supraumbilically located in 54 cases, subumbilically in 61 cases, and supra- and subumbilically in 24 cases. Postoperative complications were recorded in eight cases (5.75%): one case with a hematoma in the right abdominal muscle sheath; five cases with supra-aponeurotic seromas; two cases with skin necrosis and one with a mesh infection. Recurrence occurred in seven cases (5.03%): four cases in the first 2 years postoperatively and three cases in the third year after surgery. CONCLUSIONS The retromuscular technique with prolene mesh and a hernial sac is an effective method of restoring the integrity of the abdominal wall in large median incisional hernias with low rates of morbidity and recurrence.

Abstract
Abstract
BACKGROUND
Hemangioblastomas (HBMs) are known to exhibit very typical radiological features and thus classified by well-established radiological classification scheme. However, after we have experienced unusual cases in which current radiological classification system was not enough to categorize them, we reviewed our series of infratentorial HBMs in order not only to evaluate the relevance of current classification scheme, but also to possibly improve it. Also, we added descriptions on several cases with unusual radiological magnetic resonance imaging (MRI) findings in which differential diagnosis was challenging.
MATERIAL AND METHODS
We retrospectively reviewed preoperative MRI of 118 patients with pathologically diagnosed infratentorial HBMs at our institution between 2002 and 2015. Total 128 tumors were included to this study and classified into four categories based on the presence and nature of cystic components: extratumoral cystic (Type Ce, classical cystic with a mural nodule), intratumoral cystic (Type Ci), mixed cystic (Type Cm), and solid (Type S). The association with von Hippel-Lindau (VHL) disease was also investigated.
RESULTS
In 118 patients (65 male and 53 female), 79 (66.9%) had solitary HBMs and 39 (33.1%) were diagnosed with VHL disease. Type Ce with typical radiological findings was the most prevalent type of HBM (63.3%), followed by Type S (21.1%). HBMs with intratumoral cysts were uncommon (Type Ci, 11.7%) and mixed extratumoral and intratumoral cysts (Type Cm) accounted for only 3.9%. No intergroup differences were observed in the proportions of each subtype between the solitary and VHL disease-associated HBMs.
CONCLUSION
Radiological features of HBMs are usually typical thus preoperative presumption is not difficult in majority of cases. Improved radiological classification scheme is more practical because it does not only help surgeons determine whether the cystic wall should be removed or not, but also covers cases with atypical radiological presentations. For solid and extraparenchymal HBMs, differential diagnosis is more difficult as well as very critical as surgical removal is often very challenging.

Abstract
Salinity is a major environmental stress to plants. In this study, the ability of plants to tolerate salt was investigated by studying growth, physiological characteristics, and expression levels of genes related to the salt-stress response in the salt-tolerant rice mutant (Till-II-877), which was derived from γ-ray irradiation. Compared to plants grown under normal conditions, the height and root length of wild type (WT) were reduced by approximately 40 and 29% following exposure to salt stress for 3 weeks, whereas Till-II-877 line showed 29 and 23% reductions in plant height and root length, respectively. No significant changes were observed in total chlorophyll content, and the malondialdehyde content of the mutant increased less than that of the WT under salt treatment. Gene expression was compared between the WT and mutant lines using microarray analysis. An unbiased analysis of the gene expression datasets allowed us to identify the pathways involved in salt-stress responses. Among the most significantly affected pathways, changes in gene expression were observed in α-linolenic acid and linoleic acid metabolism (in lipid metabolism), fructose and mannose metabolism and glycolysis-gluconeogenesis (in carbohydrate metabolism), cysteine and methionine metabolism (in amino acid metabolism), and carbon fixation (in the energy metabolism of photosynthetic organisms) under salt stress. These results show that the differential response of plants subjected to salt stress was due to changes in multiple metabolic pathways. These findings increase our understanding of the effects of salt stress in rice and may aid in the development of salt-tolerant rice cultivars.

Abstract
PURPOSE There are currently no consistently effective treatments for the excessive collagen produced by keloid fibroblasts. Previously, we reported that heat shock protein 70 (Hsp70) is up-regulated in keloid fibroblasts and keloid tissue. We, therefore, investigated whether Hsp70 is related to excessive collagen production in keloid fibroblasts. MATERIALS AND METHODS We inhibited Hsp70 in keloid fibroblasts by RNA interference and examined the resulting collagen expression. Thus, we selected small interfering RNAs (siRNAs) specific for human Hsp70, transfected them into keloid fibroblasts, and evaluated the resulting phenotypes and protein production using real-time polymerase chain reaction (PCR), Western blot, and a collagen assay. RESULTS The siRNAs dramatically suppressed Hsp70 mRNA expression, resulting in a decrease in collagen production in the keloid fibroblasts compared with controls. The siRNAs did not influence the viability of the keloid fibroblasts. CONCLUSION Hsp70 overexpression likely plays an important role in the excessive collagen production by keloid fibroblasts. RNA interference has therapeutic potential for the treatment of keloids.

Abstract
PURPOSE The effectiveness of supplemental screening ultrasound (US) was investigated in women ≥ 40 years at average risk for breast cancer regardless of breast parenchymal density. A total of 4394 women at average risk and having previously undergone screening mammography were classified as the mammography group. MATERIALS AND METHODS Of 4394 women, 2005 underwent screening US after a final assessment of category 1 or 2 on screening mammography, and were categorized as the US group. Category 0, 4, and 5 on mammography and 3, 4, and 5 on US were defined as positive. The cancer yields per 1000 women and diagnostic performance of two groups were compared. RESULTS The total cancer and invasive cancer yields for the mammography group were 3.0 (95 % confidence interval 1.6, 5.1) and 2.0 (95 % CI, 0.9, 3.9) per 1000 women, higher than the US values of 2.0 (0.5, 5.1) and 1.0 (0.1, 3.6), not statistically significant. The specificity, accuracy, and positive predictive value (PPV) for mammography were 88.90 % (87.93, 89.81), 88.85 % (87.88, 89.76), and 2.61 % (1.39, 4.41), significantly higher than the US values of 69.07 % (66.99, 71.09), 69.13 % (67.05, 71.15), and 0.64 % (0.18, 1.64). The short-term follow-up rate of mammography was 5.51 % (4.85, 6.22), significantly lower than the rate of 26.58 (24.66, 28.58) for US. CONCLUSION Supplemental screening US in mammographically negative breasts can find additional carcinomas in women at average risk but is not as effective as screening mammography because of the lower cancer yield, invasive cancer yield, specificity, accuracy, PPV and a high short-term follow-up rate.

Abstract
Skin pigmentation is a complex process including melanogenesis within melanocytes and melanin transfer to the keratinocytes. To develop a comprehensive screening method for novel pigmentation regulators, we used immortalized melanocytes and keratinocytes in co-culture to screen large numbers of compounds. High-throughput screening plates were subjected to digital automated microscopy to quantify the pigmentation via brightfield microscopy. Compounds with pigment suppression were secondarily tested for their effects on expression of microphthalmia transcription factor (MITF) and several pigment regulatory genes, and further validated in terms of non-toxicity to keratinocytes/melanocytes and dose-dependent activity. The results demonstrate a high-throughput, high-content screening approach, which is applicable to the analysis of large chemical libraries using a co-culture system. We identified candidate pigmentation inhibitors from 4000 screened compounds including zoxazolamine, 3-methoxycatechol and alpha-mangostin, which were also shown to modulate expression of MITF and several key pigmentation factors and are worthy of further evaluation for potential translation to clinical use.

Abstract
AIM To present a rarely diagnosed case of gastric Dieulafoy lesion. DESCRIPTION OF CASE A 62-year-old male was hospitalized with hematemesis. Laparoscopic ligature of two gastric ulcers located in the antrum was performed but the upper gastrointestinal bleeding was not stopped. The patient was transferred to another surgical clinic and he underwent an emergency abdominal laparotomy with re-suture of gastric ulcers. Considering his general condition and another recurrent bleeding, he was transferred to our hospital and a total gastrectomy of necessity was performed. The patient died four days after surgery because of sepsis. At autopsy, we identified diffuse peritonitis, hypertrophic cardiomyopathy and chronic pancreatitis with expanded fibrotic areas. Histological examination of the surgical specimen showed oversized tortuous vessels in the gastric submucosal layer with expansion into mucosa. Some of the vessels presented acute and/or organized thrombi with recanalization, in the others, lipid-rich atherosclerotic plaques were observed. Based on these criteria, the 'caliber-persistent artery', also known as 'Dieulafoy's lesion', was diagnosed. CONCLUSION Dieulafoy's lesion should be suspected in every case of gastrointestinal bleeding in both adults and children.

Abstract
Despite thousands of studies about colorectal cancer (CRC) as much as extensively usage of prognostic antibodies÷genes and clinical trials that include the newest targeted drugs, this tumor still remains in the top of both incidence and cancer-related mortality. In this review, we intended to correlate our experience in field of colorectal cancer with the literature data and to present our vision about the prognostic and predictive role of some of the most used molecular and immunohistochemical examinations in the field. The prognostic and predictive values of parameters such as microsatellite instability, angiogenesis, Maspin gene/protein, K-ras and BRAF mutations are discussed in relationship to the classical antibodies such as Keratin 7/20, p53 or HER2. At the end, we correlated these informations and tried to realize a molecular classification of colorectal cancer, similar to breast carcinomas, in order to establish targeted groups of patients for targeted therapy.

Abstract
An 18-year-old girl with no psychiatric history presented with abdominal pain. Four months previously she had given birth to a healthy baby. On palpation, a painful abdominal mass was identified in the epigastric region, and gastrotomy was performed. A J-shaped hair-wool ball and two large pieces of sheep's wool were removed. No history of trichotillomania was reported.

Abstract
Gamma-ray line signatures can be expected in the very-high-energy (E(γ)>100 GeV) domain due to self-annihilation or decay of dark matter (DM) particles in space. Such a signal would be readily distinguishable from astrophysical γ-ray sources that in most cases produce continuous spectra that span over several orders of magnitude in energy. Using data collected with the H.E.S.S. γ-ray instrument, upper limits on linelike emission are obtained in the energy range between ∼ 500 GeV and ∼ 25 TeV for the central part of the Milky Way halo and for extragalactic observations, complementing recent limits obtained with the Fermi-LAT instrument at lower energies. No statistically significant signal could be found. For monochromatic γ-ray line emission, flux limits of (2 × 10(-7) -2 × 10(-5)) m(-2) s(-1) sr(-1) and (1 × 10(-8) -2 × 10(-6)) m(-2) s(-1)sr(-1) are obtained for the central part of the Milky Way halo and extragalactic observations, respectively. For a DM particle mass of 1 TeV, limits on the velocity-averaged DM annihilation cross section ⟨σv⟩(χχ → γγ) reach ∼ 10(-27) cm(3)s(-1), based on the Einasto parametrization of the Galactic DM halo density profile.

Abstract
Maspin is a serine protease which belongs to the serpin family and seems to play an important role in inhibiting angiogenesis and tumor proliferation. The significance of its expression in colorectal cancer (CRC) has not been elucidated so far. In our study, we tried to identify, based on Maspin expression, four groups of CRC, with possible prognostic impact. In 121 CRC, we analyzed the Maspin expression in correlation with the clinico-pathological features, microsatellite status and other markers such as p53, bax, bcl-2, VEGF (Vascular Endothelial Growth Factor) and CD31. Based on the percentage and intensity of Maspin expression in the tumor cells, the cases were grouped in four classes: negative, with cytoplasmic predominance, nuclear predominated, and cases with mixed (cytoplasmic-nuclear) expression. 9% of the cases were negative, 44% presented cytoplasmic predominance, the nuclear predominance was revealed in 24% of the cases, and the other 23% of CRC having a mixed Maspin positivity. The cytoplasmic predominance was correlated with a better prognosis, p53 negativity, bax positivity, and lack of tumor budding. Forty percent of microsatellite instable (MSI) cases presented mixed expression, this pattern being also related to a lower angiogenesis. Nuclear predominance was associated with p53 positivity, the lowest survival rate and intense VEGF expression. In conclusion, CRC with cytoplasmic predominance and mixed Maspin expression seems to present better prognosis whereas nuclear predominance is connected with high aggressivity.

Abstract
Regularly branched InN nanostructures were controllably grown onc-plane sapphire substrates by using hydride vapor phase epitaxy. On the basis of the crystallographic analysis of these InN tetrapods, it is proposed that (i) each tetrapod consists of four nanorods in the wurtzite phase protruding from a truncated tetrahedral nanocore in the zinc-blende phase and that (ii) branching occurs at the four {111} faces of the truncated tetrahedral nanocore. Our work suggests that the branching regularity of InN tetrapods is attributed to the polytypic transition at these four faces.

Abstract
Mena (mammalian Ena) is an actin regulatory protein involved in cell motility and adhesion. Based on its potential role in malignant transformation revealed in other organs, we analyzed the Mena expression in normal salivary glands (SG) and salivary tumors. Mena expression was determined in normal SG (n=10) and also benign (n=20) and malignant (n=35) lesions of SG. For the immunohistochemical staining we used the anti-Mena antibody. All normal SG and the benign lesions (10 pleomorphic adenomas, 10 Warthin's tumors) were Mena negative. Salivary duct carcinomas (n=5), carcinomas in pleomorphic adenoma (n=5), acinic cell carcinomas (n=5), squamous cell carcinomas (n=10) and high-grade mucoepidermoid carcinomas (n=2) were positive. The lymphomas (n=5) and low-grade mucoepidermoid carcinomas (n=1) were Mena negative. In one case the lymphoblastic cells stained positive for Mena. Some of the endothelial cells, in the peritumoral vessels, were Mena positive. To the best of our knowledge, this is the first study in the literature about Mena expression in salivary tumors. Our study suggests that Mena protein seems to play a role in malignant transformation and its intensity is correlated with the type and grade of tumor and also with vascular invasion. Its positivity in endothelial cells may suggest its potential role in tumor angiogenesis.

Abstract
PURPOSE To determine the histological differences and the particular aspects of local angiogenesis in knee joint of the patients with osteoarthritis (OA) and rheumatoid arthritis (RA). MATERIALS AND METHODS In 10 cases with RA and five OA, immunohistochemical stains were performed with CD31 and VEGF-A (Vascular Endothelial Growth Factor). All surgical samples provided from total knee joint arthroplasty. Angiogenesis was quantified in both synovial membrane and cartilage. RESULTS In patients with OA, villous proliferation of the synovial membrane was more prominent that in RA. In the last, invasion of the cartilage by the proliferated synovial tissue was more characteristic. The neovascularization was more intense in RA than in OA, in both synovium and degenerated cartilage. In RA, the vessels were immature in the superficial areas and became larger in the deep synovium. The local angiogenesis was characterized by sprouting and splitting (intussusceptions) mechanisms. In OA, the mature vessels predominated in the subintimal zones. Sprouting or non-sprouting mechanisms of local angiogenesis, which can indicate vascular formation from the resident mature vessels, were not identified in OA. CONCLUSIONS Angiogenesis seems to have particular behavior in RA and OA. In RA, local active angiogenesis seems to predominate but in OA up taking of the circulating precursors may be more intensely involved. Intra-articular inhibition of local angiogenesis could have therapeutically impact in RA but not in OA. Finally, we can conclude that there probably are many different pathways leading to the same joint damage having certain therapeutic consequences.

Abstract
INTRODUCTION The growth of solid tumors requires the development of microvessels, therefore tumor expansion depends on angiogenesis. Microvessels provide nutrients and oxygen and remove catabolytic substances, while endothelial cells produce growth factors for tumor cells in a paracrine fashion. The microvascular component of a tumor also plays a role in the metastatic capacity of the tumor, enabling the tumor cells to spread to distant locations by providing a large endothelial surface. AIM The purpose of this study was to review the literature about angiogenesis regarding malignant lymphomas and to perform basic measurements by means of digital morphometric methods in large B-cell lymphomas and follicular lymphomas. MATERIALS AND METHODS After thorough analyzing currently available assessment methods, we performed angiogenesis assessment on 19 randomly selected cases, from paraffin-embedded specimens using digital morphometry. We used immunohistochemistry and the CD34 antigen to mark microvessels. We measured average vascular diameter and a previously successfully applied digital morphometric method to quantify the extent of endothelial area. RESULTS According to literature data, our knowledge and understanding of angiogenesis grew rapidly from early studies such as Folkman's classic paper. Many studies showed that angiogenesis plays a key role in the biology of tumors and therefore the study of angiogenesis might open new therapeutic possibilities. There have been many studies of angiogenesis in malignant lymphomas, however not as many articles as in other tumor types. Our morphometric studies showed there are statistically significant differences between diffuse large cell lymphoma (DLBCL) and follicular lymphoma (FL) regarding average vascular diameter and that high grade lymphomas tend to have a greater CD34+ endothelial area.

Abstract
Association of aggressive jejunal carcinoid tumors and other primary gastrointestinal neoplasms are rarely observed. We describe the case of a synchronous jejunal carcinoid tumor and two colorectal polyps in a 78-year old woman. Surgical intervention was performed for the colorectal tumors and the carcinoid was incidentally found. It was well differentiated but was accompanied by lymph node metastasis and peritoneal carcinomatosis. In this case, the prognosis was not depending by the colorectal tumors but the aggressive feature of jejunal carcinoid lead to patient's death.

Abstract
A search for a very-high-energy (VHE; ≥100 GeV) γ-ray signal from self-annihilating particle dark matter (DM) is performed towards a region of projected distance r∼45-150 pc from the Galactic center. The background-subtracted γ-ray spectrum measured with the High Energy Stereoscopic System (H.E.S.S.) γ-ray instrument in the energy range between 300 GeV and 30 TeV shows no hint of a residual γ-ray flux. Assuming conventional Navarro-Frenk-White and Einasto density profiles, limits are derived on the velocity-weighted annihilation cross section (σv) as a function of the DM particle mass. These are among the best reported so far for this energy range and in particular differ only little between the chosen density profile parametrizations. In particular, for the DM particle mass of ∼1 TeV, values for (σv) above 3×10(-25) cm(3) s(-1) are excluded for the Einasto density profile.
