Abstract
The misuse of anabolic androgenic steroid associated or not with physical workouts disrupts gastrointestinal (GI) function homeostasis. Our goal was to investigate the effects of nandrolone decanoate (ND) and moderate swimming on the GI transit of solid meals, GI motor contractility, and intestinal histology in rats. Male Wistar rats were allocated to four groups that received intramuscular injections of ND (5.0 mg/kg) or vehicle (60.0 µL) and were submitted or not to swimming sessions (60 min, 5% body weight overload) for 4 weeks. Gastric emptying, intestinal transit, in vitro GI contractility, intestinal morphometry, and duodenal mucosal mast cells were evaluated in all experimental groups. ND treatment accelerated gastric emptying, slowed small intestine transit time, enhanced gastric carbachol-mediated reactivity, decreased crypt depth and villus height, reduced mucosal thickness, and increased the circular and longitudinal muscle layer thickness of the duodenum in sedentary rats. Moderate exercise accelerated intestinal transit time and reduced submucosa thickness. In vehicle-treated animals, a strong negative correlation was found between intestinal transit and mucosal mast cells, which was reversed by ND treatment. Combining ND treatment and swimming accelerated gastric emptying, increased duodenal cholinergic reactivity, inhibited the sodium nitroprusside relaxing response, increased the number of duodenal mast cells, decreased villus height, and increased the thickness of all muscle layers. ND changed the morphological and functional properties of the GI tract over time, with intense dysmotility, especially in sedentary animals, but moderate exercise seemed to have played a compensatory role in these harmful effects in the gut.

Donor-recipient intermicrobial interactions impact transfer of subspecies and fecal microbiota transplantation outcome. Cell Host Microbe 2024; 32:349-365.e4.

Abstract
Studies on fecal microbiota transplantation (FMT) have reported inconsistent connections between clinical outcomes and donor strain engraftment. Analyses of subspecies-level crosstalk and its influences on lineage transfer in metagenomic FMT datasets have proved challenging, as single-nucleotide polymorphisms (SNPs) are generally not linked and are often absent. Here, we utilized species genome bin (SGB), which employs co-abundance binning, to investigate subspecies-level microbiome dynamics in patients with autism spectrum disorder (ASD) who had gastrointestinal comorbidities and underwent encapsulated FMT (Chinese Clinical Trial: 2100043906). We found that interactions between donor and recipient microbes, which were overwhelmingly phylogenetically divergent, were important for subspecies transfer and positive clinical outcomes. Additionally, a donor-recipient SGB match was indicative of a high likelihood of strain transfer. Importantly, these ecodynamics were shared across FMT datasets encompassing multiple diseases. Collectively, these findings provide detailed insight into specific microbial interactions and dynamics that determine FMT success.

Abstract
Background: With the online proliferation of illegal substances, the Internet offers a wide variety of information on the acquisition and intake of anabolic-androgenic steroids (AAS) and other performance and image enhancing drugs. This study focuses on investigating the characteristics of the online AAS market in Central Asia. OBJECTIVES The primary objectives of this study were to investigate the accessibility and features of the online market for AAS in Central Asia. To achieve this, we employed a netnographic approach for a systematic exploration of websites advertising and selling AAS. The study aimed to conduct a comprehensive analysis of several key aspects, including the variety of AAS products offered, the quality of health advice provided the level of product availability, the procedures involved in making purchases, and the pricing structures within this market. RESULTS Twenty-one websites supplying AAS in Central Asia met our inclusion criteria. Using content analysis, data were gathered on AAS offerings, quality of health advice provided, availability, purchase process, and prices. Data were synthesized using descriptive statistics. Results indicate that AAS are easily accessible for purchase without valid medical prescription in the Central Asia online market. Most websites advertised the aesthetic and ergogenic benefits of AAS use without indicating the potential complications and adverse effects. CONCLUSIONS Public health efforts to mitigate AAS use in Central Asia should consider both the online accessibility of AAS and the lack of accompanying information on potential complications as well as adverse effects associated with their use. Efforts must be intensified to curtail the proliferation of AAS and related misleading information on the Central Asian online market.

Abstract
BACKGROUND AND AIM Spinal Cord Injury without Radiographic Abnormality (SCIWORA) represents acute traumatic myelopathy in the absence of instrumental evidence of fractures and/or dislocations of the cervical vertebrae. METHODS In this article we present 4 cases of SCIWORA that came to our observation and the medico-legal implications associated with them. RESULTS In defining the compensation in the context of a private accident policy for traumatic pathologies of the spinal cord, an in-depth medical-legal assessment is essential, based on an accurate examination of the health documentation including the instrumental investigations performed, the anamnesis and an accurate evaluation of the trauma dynamic. The paraphysiological deterioration of organ-tissue structures, identifiable in the concept of "natural variability of biological risk", should be included in the same definition of insured risk by age group, with the consequence that physical conditions that fall within the physiological or paraphysiological definitions, although potentially contributing to injury, do not necessarily exclude compensation. A different concept dominates the variability of the compensation according to a paraphysiological pre-existing condition. The two arguments therefore call for thorough consideration of both the paraphysiological contributing causes of injury and/or impairment as necessarily subject to a preliminary study, which through the clinical and instrumental investigation method, will define the perimeter of functionality.

Abstract
This study aimed to assess the effects of GH adjuvant therapy on the cumulative live birth rate in patients with poor embryo quality and to determine the characteristics of patients who are more responsive to GH. A retrospective cohort study was carried out in patients who have suffered from previous IVF failure due to poor embryonic development and underwent IVF with or without a 6-week pretreatment with GH in the subsequent cycle from January 2018 to December 2020. Clinical parameters including the cumulative live birth rate between the (-) GH and (+) GH groups were compared. Multivariate analysis was performed to ascertain associations between clinical parameters and cumulative live birth rate. Upon analysis of the clinical data from 236 IVF cycles, 84 patients received GH and 152 did not receive GH. In frozen embryo transfer cycles, compared with the (-) GH group, the implantation rate and live birth rate were significantly higher in the (+) GH group (p < 0.05). After adjusting for possible confounding factors, GH improved cumulative live birth per oocyte retrieval cycle by 1.96 folds (p = 0.032). Furthermore, when patients were subdivided based on age and BMI, a significant increase in the cumulative live birth rate was found in the (+) GH group of patients between 35 and 42 years old and BMI ≥ 24 kg/m2, respectively (p < 0.05). GH may increase the live birth rate in women who experienced IVF failure because of poor embryonic development, particularly in obese patients and women with advanced age.

Abstract
Pseudarthrosis (PSA) is a possible complication of femoral shaft fracture treatment. It is often associated with reduced bone quality and can, therefore, adversely affect quality of life. Its treatment poses a major challenge for orthopaedic surgeons. Several authors have set forth different surgical approaches for the treatment of pseudarthrosis, such as internal fixation with plate and screws, replacement of an intramedullary nail or prosthetic replacement. In cases associated with bone loss, osteopenia, or comminution of fracture fragments, autologous or homologous bone grafts may also be used. The chronic outcomes of the surgical treatment of femoral shaft pseudarthrosis, even when consolidation is achieved, are linked to disabling sequelae of clinical-functional relevance, deserving an adequate medico-legal evaluation. The purpose of this retrospective study is to analyse a clinical case series of patients treated for atrophic femoral shaft pseudarthrosis at the IRCCS Orthopaedic Institute Galeazzi, Milan, Italy, from 2014 to 2020 and their orthopaedic-traumatological and medico-legal implications.

Abstract
Aging hinders the effectiveness of regenerative medicine strategies targeting the repair of volumetric muscle loss (VML) injury. Anabolic steroids have been shown to improve several factors which contribute to the age-related decline in muscle's regenerative capacity. In this study, the impact of exogenous nandrolone decanoate (ND) administration on the effectiveness of a VML regenerative repair strategy was explored using an aged animal model. Unilateral tibialis anterior VML injuries were repaired in 18-month-aged animal models (male Fischer 344 rat) using decellularized human skeletal muscle scaffolds supplemented with autologous minced muscle. The contralateral limb was left untreated/uninjured. Following repair, ND(+) or a carrier control (ND-) was delivered via weekly injection for a period of 8 weeks. At 8 weeks, muscle isometric torque, gene expression, and tissue structure were assessed. ND(+) treatment did not improve contractile torque recovery following VML repair when compared to carrier only ND(-) injection controls. Peak isometric torque in the ND(+) VML repair group remained significantly below contralateral uninjured control values (4.69 ± 1.18vs. 7.46 ± 1.53 N mm/kg) and was statistically indistinguishable from carrier only ND(-) VML repair controls (4.47 ± 1.18 N mm/kg). Gene expression for key myogenic genes (Pax7, MyoD, MyoG, IGF-1) were not significantly elevated in response to ND injection, suggesting continued age related myogenic impairment even in the presence of ND(+) treatment. ND injection did reduce the histological appearance of fibrosis at the site of VML repair, and increased expression of the collagen III gene, suggesting some positive effects on repair site matrix regulation. Overall, the results presented in this study suggest that a decline in regenerative capacity with aging may present an obstacle to regenerative medicine strategies targeting VML injury and that the delivery of anabolic stimuli via ND administration was unable to overcome this decline.

Abstract
Performance-enhancing drugs (PEDs) are represented by several compounds used to ameliorate the image, the appearance, or an athletic or non-athletic performance. Gamma-hydroxybutyrate (GHB) is an endogenous molecule first used as anesthetic and then marketed as a nutritional supplement with a wide diffusion in the bodybuilding community. The aim of the present work is to provide a toxicological characterization of the use of GHB as a PED, including the scientific basis for its use, the patterns of use/abuse, and the health risks arising from its consumption in this peculiar recreative setting. A literature search was performed on multiple databases including experimental studies on humans and animals as well as epidemiological reports and forensic case reports/series. Experimental studies demonstrated that the use of GHB as a PED is motivated by the release of growth hormone and the induction of sleep. However, the panel of desired performance-related effects was much wider in real cases and epidemiological studies. Even though the use of GHB among bodybuilders has decreased, its use to enhance some kind of performance, particularly sexual ones or social-communicative ones, as well as means to increase mood and perceived energy, is still common.

Min T, Karthikeyan A, Lee KH. Assessment of testicular steroidogenic enzymes expression in experimental animal model following withdrawal of nandrolone decanoate. JOURNAL OF ANIMAL SCIENCE AND TECHNOLOGY 2021; 63:1247-1264. [PMID: 34957441 PMCID: PMC8672267 DOI: 10.5187/jast.2021.e102] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/18/2021] [Revised: 08/24/2021] [Accepted: 09/01/2021] [Indexed: 11/26/2022]
Abstract
Anabolic steroids are frequently used to increase the growth rate of
meat-producing animals. Exposure to an anabolic-androgenic steroid, nandrolone
decanoate (ND), is associated with expressional reduction of testicular
steroidogenic enzymes. However, the effect of withdrawal of ND exposure on the
expression of these testicular molecules has not been thoroughly explored. The
current research investigated expression changes of testicular steroidogenic
enzymes in rats at several recovery periods (2, 6, and 12 weeks) after the stop
of ND treatment with different doses (2 and 10 mg/kg body weight) for 12 weeks.
Body and testis weights were recorded, and transcript levels of molecules were
determined by quantitative real-time polymerase chain reaction (PCR). The
immunohistochemistry was used to examine the changes of immuno-intensities of
molecules. At 6 and 12 weeks of the recovery period, the 10 mg/kg ND-treated
rats were lighter than other experimental groups. The interstitial compartment
vanished by ND treatment filled up as the recovery period became longer. The
expression of steroidogenic acute regulatory protein was returned to the control
level at 12 weeks of the recovery period. Expression levels of cytochrome P450
side-chain cleavage and 17a-hydroxylase were increased in 2 mg/kg ND-treated
group at 6 weeks of the recovery period, and transcript levels of these
molecules in 2 and 10 mg/kg ND-treated groups at 12 weeks of the recovery period
were significantly lower than the control. Expression levels of
3β-hydroxysteroid dehydrogenase (HSD) type I and 17β-HSD type 3 in
2 mg/kg ND-treated group were comparable with those of control at 12 weeks of
the recovery period, but not in 10 mg/kg ND-treated group. Expression of
cytochrome P450 aromatase (Cyp19) was reverted to the control
level at 2 weeks of the recovery period. Except for Cyp19,
there was a visible increase of immuno-staining intensity of other testicular
steroidogenic enzymes in the Leydig cells as the recovery period progressed.
This research has demonstrated that the cease of ND administration could restore
the expression of testicular steroidogenic enzymes close to the normal level.
Nevertheless, a relatively long recovery period, compared to the ND-exposure
period would be required to retrieve normal expression levels of testicular
steroidogenic enzymes.

an Anabolic-Androgenic Steroid, Nandrolone Decanoate. Dev Reprod 2021; 25:245-255. [PMID: 35141450 PMCID: PMC8807133 DOI: 10.12717/dr.2021.25.4.245] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2021] [Revised: 10/30/2021] [Accepted: 11/19/2021] [Indexed: 12/02/2022]
Abstract
The spermatozoa become mature in the epididymis which is divided into initial
segment and caput, corpus, and cauda epididymis. The water movement across the
epididymal epithelium is important for creating luminal microenvironment for
sperm maturation. Aquaporins (Aqps) are water channel proteins,
and expression of Aqps is regulated by androgens. The current
research was focused to examine expressional regulation of Aqp1
and Aqp9 by an androgenic-anabolic steroid, nandrolone
decanoate (ND). The ND at the low dose (2 mg/ kg body weight/week) or high dose
(10 mg) was subcutaneously administrated into male rats for 2 or 12 weeks.
Transcript levels of Aqp1 and Aqp9 were
determined by quantitative real-time polymerase chain reaction (PCR) analyses.
In the initial segment, level of Aqp1 was decreased with 12
week-treatment, while Aqp9 level was decreased by the high dose
treatment for 12 weeks. In the caput epididymis, Aqp9
expression was decreased by the low dose treatment. The 2 week-treatment
resulted in an increase of Aqp1 level but a decrease of
Aqp9 expression in the corpus epididymis. In the corpus
epididymis, the 12 week-treatment at the low dose caused the reduction of
Aqp1 and Aqp9 levels, but the high dose
treatment resulted in an increase of Aqp1 expression and a
decrease of Aqp9 level. In the cauda epididymis,
Aqp1 expression was decreased by 2 and 12 week-treatments,
while increases of Aqp9 levels was detected with the high dose
treatment for 2 weeks and with 12 week-treatment. These findings indicate
differential regulation of Aqp1 and Aqp9
expression among epididymal segments by ND.

Abstract
INTRODUCTION The hyper-catabolic state is a devastating pathophysiological response to severe injury, infection or burns. Nandrolone decanoate (ND) is a potent anabolic steroid have many clinical indications, but not investigated in burn injuries yet. PATIENTS AND METHODS A prospective randomized control study included 40 burned patients who were treated in Burn unit from burn injuries ranged from 20 to 40%. Both groups are objectively assessed, clinically and laboratory during treatment period till full recovery from burns' injury. Recall assessment of the drug safety after many years is achieved. RESULTS ND showed highly significant results supporting its use in combating catabolic insults in burns patient. Both clinical findings and laboratory findings are correlated and highly support the use of ND in burns as new effective and safe long-lasting indication. CONCLUSION This study results showed preservation of lean body mass and protein partition, as well as the near normal nitrogen balance in burn patients. Study proposes that nandrolone decanoate could be used in safe and effective way to combat hypercatabolic impact in burn injury.

Abstract
Appearance- and performance-enhancing drugs (APEDs) are commonly used by adolescents and young adults in an effort to improve not only athletic performance but also physical and mental efficiency and sexual appearance. The rationale for using these drugs is grounded in the perceived importance of external appearance, the quest for health and youth, and the urge to boost one's sexual performances. Although APED users tend to be quite moderate overall, some specific subpopulations can display pathological use associated with high-risk behaviors. A wide and diverse range of APEDs is now easily accessible to almost anyone through backdoor online avenues. Common APEDs include anabolic-androgenic steroids, non-steroidal anabolics, anorectics, diuretics and ergo/thermogenics, nootropics or "cognition enhancers," licit and illicit psychostimulants, and finally, sexual enhancers. The use of APEDs appears linked to several psychopathological disorders of unclear prevalence, e.g., body image disorders and eating disorders, perfectionism, but also depression and loneliness. The role of personality traits related to APED use has been investigated in adolescents and young adults, in elite and amateur athletes, and in chemsexers and associated with the above-reported personality traits. The studies herein analyzed show that APED consumption in the general population is quickly growing into a public health concern. It is therefore essential to launch prevention and intervention projects aimed at promoting safe instrumental use of the body, not only in sports disciplines but also among the general population, and to promote psychological aid procedures for people with substance use issues, depression and anxiety, and body image disorders.

Abstract
Nandrolone decanoate (ND) belongs to the class II of anabolic-androgenic steroids (AAS), which is composed of 19-nor-testosterone-derivatives. AAS represent a group of synthetic testosterone that is used in clinical treatment. However, these drugs are widely abused among individuals as a means of promoting muscle growth or enhancing athletic performance. AAS in general and ND in particular have been associated with several behavioral disturbances, such as anxiety, aggressiveness and depression. A factor that contributes to the development of depression is the brain activation of indoleamine 2,3-dioxygenase (IDO), the rate-limiting enzyme of kynurenine pathway (KP). In the present study, we examined the involvement of KP in depressive phenotype induced by a ND treatment (10 mg/kg/day/s.c., for 28 days) that mimics human abuse system (e.g. supraphysiological doses) in C57B/6J mice. Our results showed that ND caused depressive like-behavior in the tail suspension test and anhedonic-like state measured in the sucrose preference test. ND administration decreased the levels of brain-derived neurotrophic factor and neurotrophin-3 and reduced Na+,K+-ATPase activity in the hippocampus, striatum and prefrontal cortex. We also found that ND elicited KP activation, as reflected by the increase of IDO activity and kynurenine levels in these brain regions. Moreover, ND decreased serotonin levels and increased 5-hydroxyindoleacetic acid levels in the brain. Treatment with IDO inhibitor 1-methyl-dl-trypthophan (1 mg/kg/i.p.) reversed the behavioral and neurochemical alterations induced by ND. These results indicate for the first time that KP plays a key role in depressive-like behavior and neurotoxicity induced by supraphysiologicaldoses of ND in mice.

Abstract
Background and Objectives: Androgens play a significant role in the development of male reproductive organs. The clinical use of synthetic testosterone derivatives, such as nandrolone, is focused on maximizing the anabolic effects and minimizing the androgenic ones. Class II anabolic androgenic steroids (AAS), including nandrolone, are rapidly becoming a widespread group of drugs used both clinically and illicitly. The illicit use of AAS is diffused among adolescent and bodybuilders because of their anabolic proprieties and their capacity to increase tolerance to exercise. This systematic review aims to focus on side effects related to illicit AAS abuse, evaluating the scientific literature in order to underline the most frequent side effects on AAS abusers’ bodies. Materials and Methods: A systematic review of the scientific literature was performed using the PubMed database and the keywords “nandrolone decanoate”. The inclusion criteria for articles or abstracts were English language and the presence of the following words: “abuse” or “adverse effects”. After applying the exclusion and inclusion criteria, from a total of 766 articles, only 148 were considered eligible for the study. Results: The most reported adverse effects (found in more than 5% of the studies) were endocrine effects (18 studies, 42%), such as virilization, gynecomastia, hormonal disorders, dyslipidemia, genital alterations, and infertility; cardiovascular dysfunctions (six studies, 14%) such as vascular damage, coagulation disorders, and arteriosus hypertension; skin disorders (five studies, 12%) such as pricking, acne, and skin spots; psychiatric and mood disorders (four studies, 9%) such as aggressiveness, sleep disorders and anxiety; musculoskeletal disorders (two studies, 5%), excretory disorders (two studies, 5%), and gastrointestinal disorders (two studies, 5%). Conclusions: Based on the result of our study, the most common adverse effects secondary to the abuse of nandrolone decanoate (ND) involve the endocrine, cardiovascular, skin, and psychiatric systems. These data could prove useful to healthcare professionals in both sports and clinical settings.

Abstract
Polydrug use among adolescence is a widespread phenomenon and has increased in the last few years. In particular, most nandrolone decanoate (Nan) abusers combine its use with cannabis (Can); thus, studying the consequences of this combination in adolescent subjects is important because potentiation of their effects may increase their neurotoxicity. The present study was designed to study the neurotoxic effects of Nan and Can, alone and in combination, in adolescent male rats by studying the behavioural, biochemical, and histopathological effects. Nan (15 mg/kg, s.c.) and Can (20 mg/kg, s.c.) were given alone or in combination to rats once daily for one month. The combined administration of Can and Nan induced learning and spatial memory deficits, hypo-locomotion, anxiety and aggression in adolescent rats as evidenced by the Morris water maze, open field, elevated plus maze, and defensive aggression tests. In parallel, rats treated with the combination showed severe deleterious effects in the hippocampal and prefrontal cortex (PFC) neural architecture along with a decrease in brain-derived neurotropic factor. Furthermore, combined administration of Can and Nan increased oxidative stress (significantly increased malondialdehyde and nitric oxide levels and reduced glutathione content), elevated brain pro-inflammatory cytokines (tumour necrosis factor alpha and interleukin 1 beta), and upregulated caspase-3, caspase-8, and caspase-9 mRNA expression and cytochrome c levels. In conclusion, abuse of both Can and Nan conferred greater neurotoxic effects than either drug alone that were at least partially attributed to oxidative stress, inflammation, and intrinsic and extrinsic apoptosis in the hippocampus and PFC of rats.

Abstract
INTRODUCTION Misuse of AAS is emergent among both genders, however, few studies were performed evaluating AAS effects on female body and none evaluate the impact of nandrolone decanoate (ND) in renal function. AIM Determine the effects of chronic treatment with ND on kidney function of female rats and evaluate the influence of oxidative stress on it. MATERIAL AND METHODS Female rats were separated into two groups (n = 8 each), the treated group (DECA), which received ND at a dose of 20 mg/kg/week (i.m), and the control group (C), which was treated with the vehicle (peanut oil, i.m.). All treatments were performed during eight weeks. After this period, 24 h urine, blood and organs (heart, gastrocnemius muscle, liver and kidney) were collected. Organ hypertrophy was calculated, and kidney collagen content was evaluated. AOPP, TBARS, SOD and catalase activity were determined in the kidney. Moreover, proteinuria and creatinine clearance were also investigated. KEY-FINDINGS Hypertrophy was observed in the liver, gastrocnemius muscle, heart and kidney. Kidney hypertrophy was followed by a reduced organ function and an increase in collagen deposition. Oxidative stress upsurge occurred in both proteins and lipids, followed by a reduction in SOD activity. SIGNIFICANCE Administration of DN in rats was followed by renal damage and kidney fibrosis due to increased oxidative stress on that organ.

Abstract
Cannabis is the most commonly used illicit drug worldwide. Although its use is associated with multiple adverse health effects, including the risk of developing addiction, recreational and medical cannabis use is being increasing legalized. In addition, use of synthetic cannabinoid drugs is gaining considerable popularity and is associated with mass poisonings and occasional deaths. Delineating factors involved in cannabis use and addiction therefore becomes increasingly important. Similarly to other drugs of abuse, the prevalence of cannabis use and addiction differs remarkably between males and females, suggesting that sex plays a role in regulating cannabinoid sensitivity. Although it remains unclear how sex may affect the initiation and maintenance of cannabis use in humans, animal studies strongly suggest that endogenous sex hormones modulate cannabinoid sensitivity. In addition, synthetic anabolic-androgenic steroids alter substance use and further support the importance of sex steroids in controlling drug sensitivity. The recent discovery that pregnenolone, the precursor of all steroid hormones, controls cannabinoid receptor activation corroborates the link between steroid hormones and the endocannabinoid system. This article reviews the literature regarding the influence of endogenous and synthetic steroid hormones on the endocannabinoid system and cannabinoid action.

Abstract
Objective Nandrolone decanoate (ND) is an anabolic-androgenic steroid frequently used for clinical treatment. However, the inappropriate use of ND results in the reduction of serum testosterone level and sperm production. The suppressive effect of ND on testosterone production has not been investigated in detail. The present study was designed to examine the effect of ND on the expression of steroidogenic enzymes in the rat testis. Methods Male Sprague Dawley rats at 50 days of age were subcutaneously administrated with either 2 or 10 mg of ND/kg body weight/week for 2 or 12 weeks. The changes of transcript and protein levels of steroidogenic enzymes in the testis were determined by real-time polymerase chain reaction and western blotting analyses, respectively. Moreover, immunohistochemical analysis was employed to determine the changes of immunostaining intensity of these enzymes. The steroidogenic enzymes investigated were steroidogenic acute regulatory protein, cytochrome P450 side chain cleavage enzyme, 17α-hydroxylase, 3β-hydroxysteroid dehydrogenase, and cytochrome P450 aromatase. Results The treatment of ND resulted in depletion of Leydig cells and sloughing of germ cells in the testis. The ND treatment caused significant expressional decreases of steroidogenic enzymes at transcript and protein levels, and the destructive effects of ND on the testis were more apparent with a higher dose and a longer period of the treatment. Evident reduction of immunostaining intensity present in Leydig cells was clearly detected by the ND treatment. Conclusion The exposure to ND in young male results not only in histological changes of the testis but also in aberrant gene expression of testicular steroidogenic enzymes, consequently leading into the reduction of testosterone production in the testis and thus likely disruption of spermatogenesis.

Abstract
Anabolic-androgenic steroids (AAS) abuse is often associated with a wide spectrum of adverse effects. These drugs are frequently abused by adolescents and athletes for esthetic purposes, as well as for improvement of their endurance and performances. In this literature review, we evaluated the correlation between AAS and anxiety or aggression. Two pathways are thought to be involved in AAS-induced behavioral disorders. Direct pathway via the amygdalo-fugal pathway, which connects the central nucleus of the amygdala to the brainstem, is involved in cognitive-emotive and homeostatic processes. The latter is modified by chronic AAS use, which subsequently leads to increased anxiety. Indirect pathways via the serotonergic, dopaminergic, and glutamatergic signals which are modified by AAS abuse in latero-anterior hypothalamus and can mediate the aggressive behavior. In conclusion, the molecular mechanisms underlying the behavioral alterations following AAS abuse is unclear and remains ambiguous as additional long-term studies aimed to understand the precise mechanisms are required.

PLoS One 2017; 12:e0178922.

Abstract
Since the increased prevalence of anabolic androgenic steroids abuse in last few decades is usually accompanied by various exercise protocols, the scope of our study was to evaluate the effects of chronic nandrolone decanoate administration in supraphysiological dose and a prolonged swimming protocol (alone and simultaneously with nandrolone decanoate) on depressive state in male rats. Simultaneously, we investigated the possible alterations in neuropeptide Y (NPY) content in blood and the hippocampus, in order to determine the role of NPY in the modulation of depressive-like behavior.Exercise induced antidepressant effects in tail suspension test (decrease of the total duration of immobility), as well as significant increase in the number of hippocampal NPY-interneurons in CA1 region. Chronic nandrolone decanoate treatment attenuated the beneficial antidepressant effects of exercise as measured by the tail suspension test parameters. Simultaneously, nandrolone decanoate treatment resulted in diminution of NPY content both in blood (decreased serum levels) and in hippocampus (the significant decrease in NPY expression in all three investigated hippocampal regions-CA1, CA2/3 and DG). Our findings indicate that alterations in serum and hippocampal NPY contents may underlie the changes in depressive state in rats. The exercise was beneficial as it exerted antidepressant effect, while chronic nandrolone decanoate treatment resulted in depressive-like behavior. Furthermore, the behavioral indicators of depression showed strong correlations with the serum levels and the hippocampal content of NPY.

Abstract
Motoneuron degeneration is the hallmark of amyotrophic lateral sclerosis (ALS). The cause and predisposing factors for sporadic ALS are still unknown. Exposure to a specific environmental risk factors in subjects with a susceptibility genotype may increase the risk of the disease. The role of physical activity and the use of anabolic steroids are still debated in epidemiological studies on patients and murine models of ALS. To assess at the cellular level the role (beneficial or detrimental) of physical exercise and the use of anabolic steroid, we here investigated, in SOD1(G93A) (mSOD1) mice and wild-type littermates, changes in the ventral horn after regular exercise, treatment with the anabolic androgenic steroid 19-nortestosterone (nandrolone), and their combination, compared with matched control sedentary mice. The experiments were pursued for several weeks until symptom onset in mSOD1 mice. Lumbar motoneurons, astrocytes and microglia were analyzed. In wild-type mice, cytological alterations of motoneurons were observed especially after nandrolone treatment. The following main findings were observed in treated mSOD1 mice versus untreated ones: i) nandrolone treatment markedly enhanced motoneuron loss; this detrimental effect was reverted by the combination with exercise, resulting in increased motoneuron survival; ii) astrocytic activation was most marked after nandrolone treatment when motoneuron damage was most severe; iii) microglia activation was most marked after physical exercise when motoneuron damage was less severe. The results indicate a vulnerability of mSOD1 motoneurons to nandrolone treatment, a potential neuroprotective effect of physical exercise, and a modulation by glial cells in the ALS murine model in the examined paradigms.

The anabolic steroid nandrolone alters cannabinoid self-administration and brain CB 1 receptor density and function. Pharmacol Res 2016; 115:209-217. [PMID: 27890818 DOI: 10.1016/j.phrs.2016.11.031] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/08/2016] [Revised: 10/21/2016] [Accepted: 11/22/2016] [Indexed: 11/27/2022]
Abstract
Clinical and pre-clinical observations indicate that anabolic-androgenic steroids can induce neurobiological changes that alter the rewarding effects of drugs of abuse. In this study, we investigated the effect of the anabolic steroid nandrolone on the rewarding properties of the cannabinoid CB1 receptor agonist WIN55,212-2 (WIN) in rats. Lister Hooded male rats were treated intramuscularly with nandrolone (15mg/kg) or vehicle for 14 consecutive days, and then allowed to self-administer WIN (12.5μg/kg/infusion) intravenously. After reaching stable drug intake, self-administration behavior was extinguished to examine drug- and cue-induced reinstatement of cannabinoid-seeking behavior. Other behavioral parameters presumed to influence drug-taking and drug-seeking behaviors were examined to gain more insight into the behavioral specificity of nandrolone treatment. Finally, animals were sacrificed for analysis of CB1 receptor density and function in selected brain areas. We found that nandrolone-treated rats self-administered up to 2 times more cannabinoid than vehicle-treated rats, but behaved similarly to control rats when tested for drug- and cue-induced reinstatement of cannabinoid-seeking behavior. Enhanced cannabinoid intake by nandrolone-treated rats was not accompanied by changes in locomotor activity, sensorimotor gating, or memory function. However, our molecular data show that after chronic WIN self-administration nandrolone-treated rats display altered CB1 receptor density and function in selected brain areas. We hypothesize that increased cannabinoid self-administration in nandrolone-treated rats results from a nandrolone-induced decrease in reward function, which rats seem to compensate by voluntarily increasing their cannabinoid intake. Altogether, our findings corroborate the hypothesis that chronic exposure to anabolic-androgenic steroids induces dysfunction of the reward pathway in rats and might represent a potential risk factor for abuse of cannabis and other drugs in humans.

Abstract
The aim of improving anti-doping efforts is predicated on several different pillars, including, amongst others, optimized analytical methods. These commonly result from exploiting most recent developments in analytical instrumentation as well as research data on elite athletes' physiology in general, and pharmacology, metabolism, elimination, and downstream effects of prohibited substances and methods of doping, in particular. The need for frequent and adequate adaptations of sports drug testing procedures has been incessant, largely due to the uninterrupted emergence of new chemical entities but also due to the apparent use of established or even obsolete drugs for reasons other than therapeutic means, such as assumed beneficial effects on endurance, strength, and regeneration capacities. Continuing the series of annual banned-substance reviews, literature concerning human sports drug testing published between October 2014 and September 2015 is summarized and reviewed in reference to the content of the 2015 Prohibited List as issued by the World Anti-Doping Agency (WADA), with particular emphasis on analytical approaches and their contribution to enhanced doping controls.

Abstract
Several classes of recreational and prescription drugs have additional effects on the heart and vasculature, which may significantly contribute to morbidity and mortality in chronic users. The study presented herein focuses on pathological changes involving the heart possibly due to anabolic androgenic steroid use. The role these hormones may play in their occurrence of sudden cardiac death is also investigated. 98 medico-legal cases including 6 anabolic androgenic steroid users were retrospectively reviewed. Autopsies, histology, immunohistochemistry, biochemistry and toxicology were performed in all cases. Pathological changes consisted of various degrees of interstitial and perivascular fibrosis as well as fibroadipous metaplasia and perineural fibrosis within the myocardium of the left ventricle. Within the limits of the small number of investigated cases, our results appear to confirm former observations on this topic and suggest anabolic androgenic steroid's potential causative role in the pathogenesis of sudden cardiac deaths in chronic users.
