Abstract
The facial plastic surgeon faces increasing competition in the aesthetic world for both surgical and nonsurgical services. Incorporating nonsurgical options in practice, such as "liquid facelifts," aesthetic services, and products, increases both patient satisfaction and office revenue stream. A successful nonsurgical practice can be built with minimal expense by focusing on the most critical and popular options to offer patients.

Abstract
Acrylamide (AA), an industrial monomer, may cause multi-organ toxicity through induction of oxidative stress and inflammation. The antioxidant properties of thymoquinone (TQ), an active constituent of Nigella sativa, have been established before. The aim of the current study was to assess the protective effects of TQ against AA-induced toxicity in rats. Forty-eight male Wistar rats were divided into six groups each of eight rats. The first group acted as a negative control and received normal saline. Groups II and III were administered TQ orally at doses of 10 and 20 mg/kg b.wt., respectively, for 21 days. The four group received AA (20 mg/kg b.wt.) for 14 days. The five and six groups were given TQ at either dose for 21 days, starting seven days before AA supplementation (for 14 days). Acrylamide intoxication was associated with significant (p < 0.05) increases in serum levels of liver injury biomarkers (alanine transferase, aspartate transferase, and alkaline phosphatase), renal function products (urea, creatinine), DNA oxidative damage biomarker (8-oxo-2'-deoxyguanosine), and pro-inflammatory biomarkers (interleukin-1β, interleukin-6, and tumor necrosis factor-α). Moreover, AA intoxication was associated with increased lipid peroxidation and nitric oxide levels, while reduced glutathione concentration and activities of glutathione peroxidase, superoxide dismutase, and catalase in the liver, kidney, and brain. TQ administration normalized AA-induced changes in most serum parameters and enhanced the antioxidant capacity in the liver, kidney, and brain tissues in a dose-dependent manner. In conclusion, the current experiment showed that TQ exerted protective and antioxidant activities against AA-induced toxicity in mice.

Abstract
Rhytidectomy, or facelift in layman's terms, is performed to reverse the appearance of facial aging. A lift can improve volume shifts with age, reposition sagging tissues, and eliminate skin redundancy. There are limitations to what can be accomplished with a facelift alone. Commonly performed adjuncts including surgery to the eyelids or brows, liposuction, and even rhinoplasty can be combined to improve the result. Further options exist that are more commonly overlooked or rarely offered to patients but can greatly enhance the surgeon's ability to remove years from the face. This article will cover some additional options that every facial plastic surgeon should be familiar with and experienced to both describe and perform.

Abstract
BACKGROUND Considering the increasing number of chemical peeling applications, also the interest in the history of chemical peelings and agents, has grown in dermatology. Research ascribes the first use of phenol as a chemical peeling agent to William Tilbury Fox (1836-1879) in 1871. Furthermore, Ferdinand von Hebra (1847-1902) is said to describe the properties of various peeling agents in 1874, and Paul Gerson Unna (1850-1929) adds resorcinol and trichloroacetic acid in 1882. OBJECTIVE To identify the first mentions of chemical peeling applications and agents in 19th-century dermatology. METHODS Nineteenth-century dermatologists were identified by an examination of literature of the last 30 years on the history of chemical peeling. Systematic examination of the medical textbooks of Hebra, Fox and Unna was conducted. It was proved whether the mentioned agents were used for chemical peeling applications. RESULTS The skin peeling property of phenol was already discovered by its first describer, the chemist Friedlieb Ferdinand Runge (1795-1867) in 1834. The Viennese dermatologist Hebra described phenol as a chemical peeling agent in 1860. Hebra and his associate Moriz Kaposi (1837-1902) stated that 'Lotio carbolica' was already used in London. Fox used phenol mostly as a disinfectant and not for chemical peelings since 1869. Unna described the chemical peeling property of salicylic acid in 1882 and gave the most comprehensive account of chemical peels of the 19th century in 1899. Unna also introduced the Gutta-percha plaster with salicylic acid and phenol. Around 1900, Unna was famous for his peeling paste with resorcinol in Germany. CONCLUSIONS A new chronology of the introduction of chemical peeling in dermatology can be drawn from the results. The German-speaking dermatology pioneered the treatment of skin diseases with chemical peelings as well as for aesthetical purposes 21 years earlier than hitherto known.

Abstract
Actinic keratoses are dysplastic proliferations of keratinocytes with potential for malignant transformation. Clinically, actinic keratoses present as macules, papules, or hyperkeratotic plaques with an erythematous background that occur on photoexposed areas. At initial stages, they may be better identified by palpation rather than by visual inspection. They may also be pigmented and show variable degrees of infiltration; when multiple they then constitute the so-called field cancerization. Their prevalence ranges from 11% to 60% in Caucasian individuals above 40 years. Ultraviolet radiation is the main factor involved in pathogenesis, but individual factors also play a role in the predisposing to lesions appearance. Diagnosis of lesions is based on clinical and dermoscopic examination, but in some situations histopathological analysis may be necessary. The risk of transformation into squamous cell carcinoma is the major concern regarding actinic keratoses. Therapeutic modalities for actinic keratoses include topical medications, and ablative and surgical methods; the best treatment option should always be individualized according to the patient.

Abstract
BACKGROUND Recipes for peelings date back to medical texts of old Egypt. The oldest medical papyri contain recipes for 'improving beauty of the skin' and 'removing wrinkles' by use of agents such as salt and soda. The Egyptian Queen Cleopatra (69-30 BC) is said to have taken bathes in donkey's milk to improve the beauty of her skin. However, little is known about other agents and peeling applications in later Greek medical textbooks. OBJECTIVE We will discover new agents and describe ancient peeling applications. First, we will have to identify ancient Greek medical terms for the modern terms 'peeling' and 'chemical peeling'. Second, on the basis of the identified terms, we will perform a systematic full-text search for agents in original sources. Third, we will categorize the results into three peeling applications: (i) cleansing, (ii) aesthetical improvement of the skin and (iii) therapy of dermatological diseases. METHODS We performed a full systematic keyword search with the identified Greek terms in databases of ancient Greek texts. Our keywords for peeling and chemical peeling are 'smēxis' and 'trīpsis'. Our keywords for agents of peeling and chemical peeling are 'smégmata', 'rhýmmata', 'kathartiká' and 'trímmata'. RESULTS Diocles (4th century BC) was the first one who mentioned 'smēxis' and 'trīpsis' as parts of daily cleansing routine. Criton (2nd century AD) wrote about peeling applications, but any reference to the agents is lost. Antyllus (2nd century AD) composed three lists of peeling applications including their agents. CONCLUSION Greek medical textbooks of Graeco-Roman antiquity report several peeling applications such as cleansing, brightening, darkening, softening and aesthetical improvement of the skin by use of peeling and chemical peeling, as well as therapy of dermatological diseases. There are 27 ancient agents for what is contemporarily called peeling and chemical peeling. We discovered more specific agents than hitherto known to research.

Abstract
The use of complementary and alternative medicines in Australia has grown significantly. Much of this growth is due to their ease of accessibility from online vendors, often marketed with claims that are not scientifically tested. Black salve is a topical escharotic compound containing the active component sanguinarine, derived from the bloodroot plant. It has been advertised as a natural treatment for skin cancer. This article reviews the current state of black salve as an alternative skin cancer treatment, discussing its distribution and regulation, and provides a summary of clinical and laboratory studies. Clinical trials in this area are lacking, with most clinical data in the form of case reports demonstrating suboptimal therapeutic and cosmetic outcomes associated with its use. However, in vitro studies of sanguinarine suggest it causes indiscriminate destruction of healthy and cancerous tissue at doses higher than 5 µM, limiting its practical utility. It is vital that members of the public are aware of the potential effects and toxicity of commercial salve products.

Abstract
Physicochemical investigation of the red alga Acanthophora spicifera (Vahl) Borgesen, collected from Al-Shoaiba coast, Red Sea, Saudi Arabia, led to the isolation of a flavone from the algal tissue with acetone. Preparative chromatography on silica gel thin-layer chromatography was used for the separation of the flavone and eluted with the methanol:chloroform:ethyl acetate (1:7:2) solvent system. The physicochemical analyses infrared, mass spectra, and ultraviolet spectra in addition to shift reagents (NaOMe, NaOAc, NaOAc + H3BO3, AlCl3, and AlCl3 + HCl) were used for the identification and elucidation of the structure of the flavone compound (4,5,7-trihydroxy flavonoids). The flavone compound was identified as apigenin bycomparing its physicochemical data with those in the literature. Analgesic and anti-inflammatory activities of apigenin were evaluated. Apigenin showed promising analgesic and anti-inflammatory activities in the hot plate test and writhing test in mice as well as tail-immersion tests and carrageenan-induced paw edema and cotton pellet-induced granuloma formation in rats. It is concluded that apigenin possesses potent analgesic, anti-inflammatory, and antiproliferative activities, which might be due to the inhibition of PGE2 as well as proinflammatory cytokines such as interleukin-1β, interleukin-6, and tumor necrosis factor-α.

Abstract
Thallium acetate (TI) is a cumulative poison intimately accompanied by an increase in reactive oxygen species (ROS) formation that represents an important risk factor for tissue injury and malfunction. This study aims to determine the possible hepatoprotective and antioxidant effects of diallyl sulfide (DAS) from garlic and curcumin from turmeric against TI-induced liver injury and oxidative stress (OS) in rats. This in vivo animal study divided rats into six groups of 8 rats per group. The first group received saline and served as the control group. The second and third groups received DAS or curcumin only at a dose of 200 mg/kg. The fourth group received TI at a dose of 6.4 mg/kg for 5 consecutive days. The fifth and sixth groups received DAS or curcumin orally 1 hour before TI intoxication at the same dose as the second and third groups. Liver integrity serum enzymes aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), and γ-glutamyltransferase (γ-GT) were evaluated. Serum and liver tissue homogenate lipid peroxidation and OS biomarkers were measured. The data were analyzed by one-way ANOVA followed by Duncan's multiple range test for post hoc analysis using SPSS version 16. TI induced marked oxidative liver damage as shown by significantly (P≤0.05) elevated serum AST, ALT, ALP, LDH and γ-GT levels. There were significant (P≤0.05) increases in serum and hepatic malondialdehyde (MDA) and serum nitric oxide (NO) as well as decreased hepatic glutathione (GSH) and catalase (CAT) activities. There were significantly (P≤0.05) less serum and hepatic superoxide dismutase (SOD) and total antioxidant capacity (TAC). Pre-treatment with DAS or curcumin ameliorated the changes in most studied biochemical parameters. DAS and curcumin effectively reduced TI-induced liver toxicity.

Abstract
Objective Tilmicosin (TIL) is a long-acting macrolide antibiotic used to treat cattle for
pathogens that cause bovine respiratory disease. However, overdoses of this medication
have been reported to induce cardiac damage. Our experimental objective was to evaluate the protective effects of Spirulina platensis (SP) administration against TIL-induced
cardiotoxicity in mice.
Materials and Methods Our experimental in vivo animal study used 40 male albino mice
that were divided into five groups of eight mice per group. The first group served as a control
group and was injected with saline. The second group received SP at dose of 1000 mg/kg
body weight for five days. The third group received a single dose of TIL (75 mg/kg, subcutaneously). Groups 4 and 5 were given SP at doses of 500 and 1000 mg/kg body weight for five
consecutive days just before administration of TIL at the same dose and regimen used for
group 3.
Results TIL treated animals showed a significant increase in serum cardiac injury biomarkers as well as cardiac lipid peroxidation, however they had evidence of an inhibition in antioxidant biomarkers. SP normalized elevated serum levels of lactate dehydrogenase (LDH),
creatine kinase (CK), and CK-MB. Furthermore, SP reduced TIL-induced lipid peroxidation
and oxidative stress in a dose-dependent manner.
Conclusion Administration of SP minimized the toxic effects of TIL by its free radicalscavenging and potent antioxidant activity.

Abstract
Infrared radiation A (IRA) is absorbed by melanin and generates heat. Therefore, the effect of IRA could be well analyzed using skin, which contains melanin in the epidermis. Hairless mice harboring epidermal melanocytes that produce eumelanin, pheomelanin, or non-melanin were generated by backcrossing K14-stem cell factor mice, recessive yellow mice, and then albino hairless mice. High-dose IRA was irradiated over 18 weeks after the establishment of photoaged mice by irradiation with ultraviolet B (UVB) three times a week for 14 weeks. Tumor formation was assessed every week. The formation of cyclobutane pyrimidine dimer and apoptotic cells by the irradiation of IRA and UVB was evaluated. Repetitive irradiation of IRA did not promote tumor formation in all types of mice. Pre-irradiation of IRA to UVB, but not post-irradiation, accelerated the elimination of cyclobutane pyrimidine dimers and enhanced apoptosis; these effects were most obvious in eumelanin-producing mice. Real-time polymerase chain reaction analysis showed downregulation of FLICE (cellular caspase 8)-like inhibitory protein and B-cell lymphoma-extra large and upregulation of Bcl-2-associated X protein by UVB, but further enhancement of these molecules by pre-irradiation of IRA was not observed. These results indicate that IRA does not confer the promotion of UVB-induced carcinogenesis in photoaged mice harboring epidermal melanocytes and that photochemical reaction between IRA and melanin might be involved in the induction of apoptosis and the elimination of cyclobutane pyrimidine dimers by UVB. The enhancement of apoptosis by pre-irradiation of IRA to UVB might be induced by mechanisms other than the modification of the mRNA expression of FLICE (cellular caspase 8)-like inhibitory protein, B-cell lymphoma-extra large, and Bcl-2-associated X.

Abstract
Allicin, the main biologically active component of garlic clove extracts, has been evaluated for its' efficacy in preventing deltamethrin-induced oxidative damage in Nile tilapia; Oreochromis niloticus. Fish were fed on 2 different doses of 0.5 g and 1 g of allicin/kg diet for 28 days. Serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), cholesterol, urea, uric acid, creatinine, total protein, albumin and globulin were estimated. Moreover, the level of malonaldehyde (MDA) was analyzed as a lipid peroxidation marker. In addition, reduced glutathione (GSH), glutathione peroxidase (GSH-Px), superoxide dismutase (SOD) and catalase (CAT) were analyzed as antioxidant biomarkers in liver, kidney and gills. Results show that deltamethrin subacute intoxication (1.46 µg/L for 28 days) increased serum AST, ALT, ALP, cholesterol, urea, uric acid, creatinine and tissue MDA. At the same time, serum total protein and albumin as well as tissue level of GSH, GSH-Px, SOD and CAT were reduced. Allicin supplemented diets enhanced all the altered serum biochemical parameters as well as tissues' lipid peroxidation and antioxidant biomarkers in a dose-dependent manner. The results suggest that feeding allicin can ameliorate deltamethrin-induced oxidative stress and might have some therapeutic properties to protect Nile tilapia on subacute deltamethrin toxicity.

Abstract
Acrylamide is a hazardous substance inducing oxidative stress. Based on some evidence on the antioxidant properties of fenugreek, Trigonella foenum-graecum, this study was conducted to investigate the protective effect of fenugreek seed oil against acrylamide toxicity. Thirty-two male Wistar rats were randomly assigned into four groups. The control group was given normal saline. The second group was administered acrylamide (20 mg/kg bw orally). The third and fourth groups were administered acrylamide (20 mg/kg bw) and supplemented with 2.5% and 5% fenugreek seed oil in their diets, respectively. Acrylamide intoxication significantly increased serum levels of LDH, AST, ALT, APL, γ-GT, cholesterol, uric acid, urea, creatinine, 8-oxo-2'-deoxyguanosine, interleukin 1 beta, interleukin 6, and tumor necrosis factor α. Moreover, it increased hepatic, renal, and brain lipid peroxidation, while it impaired the activities and concentrations of the antioxidant biomarkers. Fenugreek oil supplementation normalized the altered serum parameters, prevented lipid peroxidation, and enhanced the antioxidant biomarker concentrations and activities in the hepatic, renal, and brain tissues of acrylamide-intoxicated rats in a dose-dependent manner. Thus, these results indicate that Trigonella foenum-graecum oil has a protective effect against acrylamide-induced toxicity through its free radical scavenging and potent antioxidant activities.

Abstract
Alpha-lipoic acid (ALA) is a natural dithiol compound, with a free radical scavenger and biological antioxidant properties. The purpose of the current study was to investigate the protective effects of ALA on biochemical alteration and oxidative stress induced by acute deltamethrin intoxication in rats. Markers of liver and kidney injuries in serum of deltamethrin-intoxicated as well as ALA-pretreated rats were analyzed. Moreover, serum and (or) tissue lipid peroxidation, malondialdehyde and antioxidant markers, reduced glutathione, catalase, superoxide dismutase activity, and total antioxidant capacity were evaluated. The results showed that all parameters were altered in the intoxicated group, indicating hepatorenal oxidative damage of deltamethrin. Pre-treatment with ALA reversed the changes in most of the studied parameters in a dose-dependent manner. Histopathological and biochemical findings were parallel. It can be concluded that ALA may be a promising therapeutic option for prevention and (or) treatment of deltamethin toxicity.

Abstract
Diazinon (DZN) is a synthetic organophosphrus acaricide and insecticide widely used for veterinary and agricultural purposes. However, its animal and human exposure leads to nephrotoxicity. Our experimental objective was to evaluate protective effects of ceftriaxone and/or ascorbic acid-vitamin C against DZN-induced renal injury in male Wistar albino rats. DZN-treated animals revealed significant elevation in serum biochemical parameters related to renal injury: urea, uric acid and creatinine. DZN intoxication significantly increased renal lipid peroxidation, and significant inhibition in antioxidant biomarkers including, reduced glutathione, glutathione peroxidase, superoxide dismutase, catalase and total antioxidant capacity. In addition, DZN significantly reduced serum acetylcholinestrase level. Moreover, It induced serum and kidney tumor necrosis factor-α level. Both ceftriaxone and vitamin C protect against DZN-induced serum as well as renal tissue biochemical parameters when used alone or in combination along with DZN-intoxication. Furthermore, both ceftriaxone and vitamin C produced synergetic nephroprotective and antioxidant effects. Therefore, it could be concluded that ceftriaxone and/or vitamin C administration are able to minimize the toxic effects of DZN by its free radical-scavenging and potent antioxidant activity.

Abstract
Trigonella foenum-graecum L. is enriched with many active ingredients. TFG oil was evaluated for its protective effect against deltamethrin toxicity in rats. Rats of the control group were administered saline. The 2nd group was administered deltamethrin (DLM) orally at a concentration of 15 mg/kg body mass. The 3rd and 4th groups were administered DLM at a concentration of 15 mg/kg body mass and were fed diets containing 2.5% and 5% TFG oil, respectively. DLM intoxication reduced red blood cell and platelet counts, hemoglobin concentration, and hematocrit value while it induced leucocytosis. Furthermore, it increased serum levels of lactate dehydrogenase, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, γ-glutamyltransferase, triglycerides, cholesterol, uric acid, urea, and creatinine; increased hepatic, renal, and brain lipid peroxidation; decreased serum acetylcholine esterase level; and decreased hepatic, renal, and brain antioxidant markers’ activities. However, TFG oil kept the studied hematological and biochemical parameters within normal ranges. In addition, it prevented lipid peroxidation and oxidative stress induced by DLM intoxication in a dose-dependent manner. Therefore, these results indicated that TFG oil inhibited the toxic effects of DLM on hematological and biochemical parameters as well as oxidative status by its free radical scavenging and potent antioxidant activities, and it appeared to be a promising protective agent against DLM-induced toxicity.

Abstract
The strychnine tree (Strychnos nux-vomica L.) (S. nux-vomica) belonging to family Loganiaceae has been a very promising medication for certain disorders. Different chromatographic methods were used to isolate the phenolic compounds from the aqueous methanolic extract of the S. nux-vomica leaves. Their identification was achieved through spectroscopic techniques. Cytotoxicity, analgesic, antipyretic and anti-inflammatory activities of S. nux-vomica leaves extract were evaluated. Five phenolic compounds were isolated and identified; Kaempferol-7 glucoside 1, 7-Hydroxy coumarin 2, Quercetin-3-rhamnoside 3, Kaempferol 3-rutinoside 4, and Rutin 5. Furthermore, the cytotoxic activity of the extract was evaluated against different cancer cell lines. The extract showed potential cytotoxic activity against human epidermoid larynx carcinoma cells (Hep-2) and against breast carcinoma cell line (MCF-7). Colon carcinoma cells (HCT) were the least one affected by the extract. In addition, the extract exhibited promising analgesic, antipyretic as well as anti-inflammatory activities. It is concluded that, leaves extract of S. nux vomica possess potent cytotoxic, analgesic, antipyretic and anti-inflammatory activities. These activities could be due to the presence of phenolic compounds revealed by our phytochemical investigations.

Abstract
An article titled "Current issues in dermatologic office-based surgery" was published in the JAAD in October 1999 (volume 41, issue 4, pp. 624-634). The article was developed by the Joint American Academy of Dermatology/American Society for Dermatologic Surgery Liaison Committee. A number of subjects were addressed in the article including surgical training program requirements for dermatology residents and selected advances in dermatologic surgery that had been pioneered by dermatologists. The article concluded with sections on credentialing, privileging, and accreditation of office-based surgical facilities. Much has changed since 1999, including more stringent requirements for surgical training during dermatology residency, and the establishment of 57 accredited Procedural Dermatology Fellowship Training Programs. All of these changes have been overseen and approved by the Residency Review Committee for Dermatology and the Accreditation Committee for Graduate Medical Education. The fertile academic environment of academic training programs with interaction between established dermatologic surgeons and fellows, as well as the inquisitive nature of many of our colleagues, has led to the numerous major advances in dermatologic surgery, which are described herein.

Abstract
Chemical peeling is one of the dermatological treatments available for certain cutaneous diseases and conditions or improvement of cosmetic appearance of photoaged skin. However, it needs to be clarified whether the repetitive procedure of chemical peeling on photodamaged skin is safe and whether the different chemicals used for peeling results in similar outcomes or not. In this article, we reviewed the effect of peeling or peeling agents on the skin in relation to ultraviolet (UV) radiation. The pretreatment of peeling agents usually enhance UV sensitivity by inducing increased sunburn cell formation, lowering minimum erythematous dose and increasing cyclobutane pyrimidine dimers. However, this sensitivity is reversible and recovers to normal after 1-week discontinuation. Using animals, the chronic effect of peeling and peeling agents was shown to prevent photocarcinogenesis. There is also an in vitro study using culture cells to know the detailed mechanisms of peeling agents, especially on cell proliferation and apoptotic changes via activating signalling cascades and oxidative stress. It is important to understand the effect of peeling agents on photoaged skin and to know how to deal with UV irradiation during the application of peeling agents and treatment of chemical peeling in daily life.
