Abstract
BACKGROUND Nanoparticle-based drugs are new inventions in the management of the Human immunodeficiency virus (HIV) pandemic, especially resistant forms of the virus in anatomical sanctuary sites and organs such as the testis. However, safety issues must be resolved to attain the optimal potential of newer nano-drug formulations. AIM The study investigated the toxicological potential of synthesized Tenofovir Nanoparticles (TDF-N) on testicular indices when used for the prevention and treatment of HIV. METHODOLOGY Fifteen male Sprague-Dawley (SD) rats with weight ranging from 230 g to 250 g were randomly assigned into groups A (control, saline), B (TDF), and C (TDF-N). The testes were removed for sperm analysis and processed for H/E and PAS stains. Cell counts and cellular measurements; the diameter and the area of the testicular seminiferous tubules were measured using ImageJ and Leica software 2.0. RESULTS A significant reduction (p < 0.05) in sperm count was noticed in the TDF-N group. Also observed in the TDF and TDF-N groups was a significant reduction (p < 0.05) in sperm motility and in the number of dead sperms compared with the control. Sperm abnormalities such as distorted basement membranes, loss of germ cells, hypocellular interstitium, and loss of spermatogenic series were increased in the TDF and TDF-N groups. There was also a significant reduction (p < 0.05) in the cell count, diameter, and area of seminiferous tubules observed in these groups. CONCLUSION TDF and TDF-N may be detrimental to the testis and testicular tissue, leading to significantly reduced sperm counts, motility, and ultimately-male fertility.

Abstract
Chemical penetration enhancer (CPE) is a preferred approach to improve drug permeability through the skin, due to its unique advantages of simple use and high compatibility. However, CPEs efficiency and safety problems frequently arise, which greatly restrains the further application in transdermal drug delivery systems (TDDS). To get access to the root of problems, the efficiency and safety of CPEs are reviewed especially from molecular perspectives, which include (1) the possible factors of CPEs low efficiency; (2) the possible contribution of CPEs in the evolution of safety problems such as skin irritation and allergic reaction; (3) the interactive relationship between CPEs efficiency and safety, as well as the bottlenecks of achieving their balance. More importantly, based on these, recent advances are summarized in improving efficiency or safety of CPEs, which offers a guidance of rationally selecting CPEs in future research.

Abstract
Fight against antimicrobial resistance calls for innovative strategies that can target infection sites and enhance activity of antibiotics. Herein is a pH responsive multilamellar vesicles (MLVs) for targeting bacterial infection sites. The vancomycin (VCM) loaded MLVs had 62.25 ± 8.7 nm, 0.15 ± 0.01 and -5.55 ± 2.76 mV size, PDI and zeta potential, respectively at pH 7.4. The MLVs had a negative ZP at pH 7.4 that switched to a positive charge and faster release of the drug at acidic pH. The encapsulation efficiency was found to be 46.34 ± 3.88 %. In silico studies of the lipids, interaction suggested an energetically stable system. Studies to determine the minimum inhibitory concentration studies (MIC) showed the MLVs had 2-times and 8-times MIC against Staphylococcus aureus (SA) and Methicillin resistance SA respectively at physiological pH. While at pH 6.0 there was 8 times reduction in MICs for the formulation against SA and MRSA in comparison to the bare drug. Fluorescence-activated Cell Sorting (FACS) studies demonstrated that even with 8-times lower MIC, MLVs had a similar elimination ability of MRSA cells when compared to the bare drug. Fluorescence microscopy showed MLVs had the ability to clear biofilms while the bare drug could not. Mice skin infection models studies showed that the colony finding units (CFUs) of MRSA recovered from groups treated with MLVs was 4,050 and 525-fold lower than the untreated and bare VCM treated groups, respectively. This study demonstrated pH-responsive multilamellar vesicles as effective system for targeting and enhancing antibacterial agents.

Abstract
Gold nanoparticles (AuNP) have attracted ample attention as a transdermal (TND) drug delivery platform for improving the skin permeability of drug molecules. Herein a novel TND device formed from AuNP and oleylamine functionalized nanodiamond (AuD) has been developed successfully for the TND delivery of Ketoprofen (KP), a model drug. Poly(vinyl alcohol)/Polybutyl methacrylate (PVA/PBMA) film has been selected as the matrix of the TND device, as they furnish excellent skin adhesion properties. The PVA/PBMA membranes loaded with different concentrations of AuD have been characterized in terms of surface morphology, thermomechanical properties, water vapor permeability (WVP), optical transmittance, cosmetic attractiveness, skin adhesion behavior, and drug encapsulation efficiency (DEE). The matrix loaded with 3.0% AuD displayed enhanced thermomechanical and DEE due to the uniform distribution of nanofillers in the membrane. The in vitro skin permeation test proved that a higher amount of KP was delivered by AuD incorporated films, suggesting improved TND behavior. The synergistic management of AuNP and nanodiamonds (ND) has caused the enhanced skin permeation behavior of the device. The obtained results revealed that AuD may be employed as an effective carrier to substitute NDs for TND delivery. Additionally, while investigating the storage stability of the device we observed that the membrane kept at low temperature presented stability over time. More importantly, the results from cell viability assay and environmental fitness test revealed that the AuD based TND system is a high security device, as it is noncytotoxic and microbe-resistant. The developed device provides a novel and handy approach to the TND delivery of drug molecules.

Abstract
Tenofovir nanoparticles are novel therapeutic intervention in human immunodeficiency virus (HIV) infection reaching the virus in their sanctuary sites. However, there has been no systemic toxicity testing of this formulation despite global concerns on the safety of nano drugs. Therefore, this study was designed to investigate the toxicity of Tenofovir nanoparticle (NTDF) on the liver and kidney using an animal model. Fifteen adult male Sprague-Dawley (SD) rats maintained at the animal house of the biomedical resources unit of the University of KwaZulu-Natal were weighed and divided into three groups. Control animals (A) were administered with normal saline (NS). The therapeutic doses of Tenofovir (TDF) and nanoparticles of Tenofovir (NTDF) were administered to group B and C and observed for signs of stress for four weeks after which animals were weighed and sacrificed. Liver and kidney were removed and fixed in formal saline, processed and stained using H/E, PAS and MT stains for light microscopy. Serum was obtained for renal function test (RFT) and liver function test (LFT). Cellular measurements and capturing were done using ImageJ and Leica software 2.0. Data were analysed using graph pad 6, p values < 0.05 were significant. We observed no signs of behavioural toxicity and no mortality during this study, however, in the kidneys, we reported mild morphological perturbations widening of Bowman's space, and vacuolations in glomerulus and tubules of TDF and NTDF animals. Also, there was a significant elevation of glycogen deposition in NTDF and TDF animals when compared with control. In the liver, there were mild histological changes with widening of sinusoidal spaces, vacuolations in hepatocytes and elevation of glycogen deposition in TDF and NTDF administered animals. In addition to this, there were no significant differences in stereological measurements and cell count, LFT, RFT, weight changes and organo-somatic index between treatment groups and control. In conclusion, NTDF and TDF in therapeutic doses can lead to mild hepatic and renal histological damage. Further studies are needed to understand the precise genetic mechanism.

Abstract
Improvements in permeation enhancement strategies, such as nanoemulsions (NEs) and nanoemulgels (NEGs), have led to a renewed interest in transdermal drug delivery (TDD). This study aimed to investigate the potential of LLA1E, a novel dendritic permeation enhancer, as an oily phase in the development of a NEG for the TDD of tenofovir (TNF). TNF loaded NEs (TNEs) were prepared and analysed for mean globule diameter (MGD), polydispersity index (PDI), zeta potential (ZP) and morphology. NEGs of the TNEs (TNEGs) were prepared and evaluated for ex vivo transdermal permeation efficacy. The skin integrity before and after the experiments was assessed using histology and transepithelial electrical resistance (TEER). TNEs had a MGD of 129.06±3.35nm, a PDI of 0.192±0.038 and a ZP of 20.9±2.02mV, with an incorporation efficiency of 91.94±0.84%. There was no significant change is these properties after incorporating the TNEs into the hydrogel, as MGD, PDI and ZP of TNEGs were found to be 136.13±5.21nm, 0.182±0.020 and -20.9±2.08mV respectively. Ex vivo permeation studies showed that the TNEG significantly enhanced the TNF permeation by 39.65-fold, with a cumulative amount of 1866.54±108.62μgcm-2. Histological and TEER assessments showed no permanent effects on the skin by TNEG, indicating that this novel TNEG nanosystem has the potential to translate into clinical trials as treatment alternatives for HIV/AIDs patients.
