Abstract
Triple-negative breast cancer (TNBC) is the most aggressive and fatal breast cancer subtype. Nowadays, chemotherapy remains the standard treatment of TNBC, and immunotherapy has emerged as an important alternative. However, the high rate of TNBC recurrence suggests that new treatment is desperately needed. Schisandrin B (Sch B) has recently revealed its anti-tumor effects in cancers such as cholangiocarcinoma, hepatoma, glioma, and multi-drug-resistant breast cancer. However, there is still a need to investigate using Sch B in TNBC treatment. Interleukin (IL)-1β, an inflammatory cytokine that can be expressed and produced by the cancer cell itself, has been suggested to promote BC proliferation and progression. In the current study, we present evidence that Sch B can significantly suppress the growth, migration, and invasion of TNBC cell lines and patient-derived TNBC cells. Through inhibition of inflammasome activation, Sch B inhibits interleukin (IL)-1β production of TNBC cells, hindering its progression. This was confirmed using an NLRP3 inhibitor, OLT1177, which revealed a similar beneficial effect in combating TNBC progression. Sch B treatment also inhibits IL-1β-induced EMT expression of TNBC cells, which may contribute to the anti-tumor response.

Abstract
Breast cancer (BC) is a common malignancy in women, with hormone receptor (HR)-positive subtype responsible for approximately 70% of cases. Currently, patients with metastatic HR-positive BC rely on endocrine therapy and cyclin-dependent kinase (CDK)-4/6 inhibitors for treatment. Currently, approved CDK4/6 inhibitors include palbociclib, ribociclib, and abemaciclib. However, clinical evidence of CDK-4/6 inhibitor resistance is emerging, suggesting that the gap in the knowledge of its resistance mechanism requires further investigation. This review discusses the mechanisms of CDK4/6 inhibitor resistance in BC, including both intrinsic and extrinsic mechanisms. We also discuss possible alternative strategies to overcome CDK4/6 inhibitor resistance in future clinical applications.

Abstract
Metaplastic breast carcinoma is an invasive carcinoma with a high differentiation rate of the neoplastic epithelium toward mesenchymal-like epithelium. It comprises of only less than 1% of all breast cancers. Although 80% to 90% of metaplastic breast carcinomas are triple-negative cancers, they usually have worse outcomes than other triple-negative breast cancers (TNBCs). Metaplastic carcinoma is also often refractory to cytotoxic chemotherapy. Here, we reported a case of a 61-year-old female patient, presenting with a solitary and pedunculated mass in the right axillary tail breast tissue, whose biopsy revealed metaplastic breast carcinoma with chondroid differentiation. She had failed neoadjuvant chemotherapy and immunotherapy. Although she received debulking surgery, the tumor regrew even faster before surgery. Despite receiving palliative chemotherapy, the patient died 11 weeks after surgery. This case draws attention to physicians that early recognition and surgery may be more beneficial than chemotherapy in combating metaplastic breast carcinoma.

Abstract
BACKGROUND Acinetobacter nosocomialis (A. nosocomialis) is a glucose non-fermentative, gram-negative bacillus that belongs to the Acinetobacter calcoaceticus-baumannii complex. In recent years, studies have found an increased clinical prevalence of A. nosocomialis. However, given the increasing trend of antibiotic resistance, developing new antibacterial agents is vital. Currently, research regarding bacteriophage therapy against A. nosocomialis is only limited. METHODS Two A. nosocomialis bacteriophages, TCUAN1 and TCUAN2, were isolated from sewage. Experiments such as transmission electron microscopy (TEM), host-range analysis, and sequencing were performed to determine their biological and genomic characteristics. TCUAN2 were further subjected to in vivo experiments and their derived-endolysin were cloned and tested against their bacteria host. RESULTS Transmission electron microscopy revealed that TCUAN1 and TCUAN2 belong to Myoviridae and Podoviridae, respectively. Both phages show a broad host spectrum and rapid adsorption efficiency. Further biological analysis showed that TCUAN2 possesses a shorter latent period and larger burst size compared to TCUAN1. Because TCUAN2 showed a better antibacterial activity, it was injected into A. nosocomialis-infected mice which resulted in a significant decrease in bacterial load levels in the blood and increased the mice's survival. Finally, genomic analysis revealed that the complete nucleotide sequence of TCUAN1 is 49, 691 bps (containing 75 open reading frames) with a G + C content of 39.3%; whereas the complete nucleotide sequence of TCUAN2 is 41, 815 bps (containing 68 open reading frames) with a G + C content of 39.1%. The endolysin gene cloned and purified from TCUAN2 also showed antibacterial activity when used with a chelator EDTA.

Abstract
Interleukin (IL)-8 plays a vital role in regulating inflammation and breast cancer formation by activating CXCR1/2. We previously designed an antagonist peptide, (RF16), to inhibits the activation of downstream signaling pathways by competing with IL-8 in binding to CXCR1/2, thereby inhibiting IL-8-induced chemoattractant monocyte binding. To evaluate the effect of the RF16 peptide on breast cancer progression, triple-negative MDA-MB-231 and ER-positive MCF-7 breast cancer cells were used to investigate whether RF16 can inhibit the IL-8-induced breast cancer metastasis. Using growth, proliferation, and invasiveness assays, the results revealed that RF16 reduced cell proliferation, migration, and invasiveness in MDA-MB-231 cells. The RF16 peptide also regulated the protein and mRNA expressions of epithelial-mesenchymal transition (EMT) markers in IL-8-stimulated MDA-MB-231 cells. It also inhibited downstream IL-8 signaling and the IL-8-induced inflammatory response via the mitogen-activated protein kinase (MAPK) and Phosphoinositide 3-kinase (PI3K) pathways. In the xenograft tumor mouse model, RF16 synergistically reinforces the antitumor efficacy of docetaxel by improving mouse survival and retarding tumor growth. Our results indicate that RF16 significantly inhibited IL-8-stimulated cell growth, migration, and invasion in MDA-MB-231 breast cancer cells by blocking the activation of p38 and AKT cascades. It indicated that the RF16 peptide may serve as a new supplementary drug for breast cancer.

Abstract
Excessive alcohol consumption can lead to serious health complications, with liver and neurological complications being the most important. In Western nations, alcoholic liver disease accounts for 50% of mortality from end-stage liver disease and is the second most common cause of liver transplants. In addition to direct damage, hepatic encephalopathy may also arise from alcohol consumption. However, effective treatment for liver disease, as well as neurological injury, is still lacking today; therefore, finding an efficacious alternative is urgently needed. In the current study, the preventive and therapeutic effects of Schisandrin B (Sch B) against ethanol-induced liver and brain injuries were investigated. By using two treatment models, our findings indicated that Sch B can effectively prevent and ameliorate alcoholic liver diseases, such as resolving liver injuries, lipid deposition, inflammasome activation, and fibrosis. Moreover, Sch B reverses brain damage and improves the neurological function of ethanol-treated mice. Therefore, Sch B may serve as a potential treatment option for liver diseases, as well as subsequential brain injuries. Furthermore, Sch B may be useful in preventive drug therapy against alcohol-related diseases.

Abstract
BACKGROUND In most developing or undeveloped countries, patients are often co-infected with multiple pathogens rather than a single pathogen. While different pathogens have their impact on morbidity and mortality, co-infection of more than one pathogen usually made the disease outcome different. Many studies reported the co-infection of Schistosoma with Salmonella in pandemic areas. However, the link or the underlying mechanism in the pathogenesis caused by Schistosoma-Salmonella co-infection is still unknown. METHODS In this study, Salmonella typhimurium (S. typhimurium) was challenged to Schistosoma mansoni (S. mansoni)-infected mice. Further experiments such as bacterial culture, histopathological examination, western blotting, and flow cytometry were performed to evaluate the outcomes of the infection. Cytokine responses of the mice were also determined by ELISA and real-time quantitative PCR. RESULTS Our results demonstrated that co-infected mice resulted in higher bacterial excretion in the acute phase but higher bacterial colonization in the chronic phase. Lesser egg burden was also observed during chronic schistosomiasis. Infection with S. typhimurium during schistosomiasis induces activation of the inflammasome and apoptosis, thereby leading to more drastic tissue damage. Interestingly, co-infected mice showed a lower fibrotic response in the liver and spleen. Further, co-infection alters the immunological functioning of the mice, possibly the reason for the observed pathological outcomes. CONCLUSION Collectively, our findings here demonstrated that S. mansoni-infected mice challenged with S. typhimurium altered their immunological responses, thereby leading to different pathological outcomes.

Abstract
BACKGROUND Schistosomiasis is one of the most devastating tropical diseases in the world. Currently, praziquantel (PZQ) represents the best pharmacological option for the treatment of schistosomiasis as it effectively kills the worm. However, the inability to reverse established liver damages often makes treatment futile. In the current study, we investigate whether combining the use of wogonin, a compound that was found to be liver-protective, with PZQ can attribute to the greatest beneficial effect in Schistosoma mansoni-infected mice. METHODS To determine the protective effect of PZQ-wogonin treatment on S. manosni-infected mice, histopathological analysis was done to evaluate the granuloma size and fibrotic areas in the liver. Western blotting was performed to analyze several injuries-related markers including fibrotic markers, inflammasomes, and apoptotic markers. Scanning electron microscopy was done to evaluate the effect of wogonin on the worms, and the worm and egg burden was calculated. RESULTS Our results showed that PZQ-wogonin treatment significantly improved liver histopathology of S. mansoni-infected mice. Further analysis showed that PZQ-wogonin combinations are more effective in reducing fibrosis, inflammation, and apoptosis in the liver than that of individual drug use. Furthermore, our results revealed that wogonin is anthelmintic; and it works better with PZQ in reducing hepatic egg burden, further lessen the disease progression. CONCLUSION In general, this combinatorial strategy may represent a new and effective approach to schistosomiasis treatment.

Abstract
BACKGROUND Elizabethkingia anophelis is an opportunistic pathogen that infects newborns and immunocompromised patients. Because the infection is associated with high mortality as a result of its intrinsic resistance to antibiotics, alternative treatment methods are needed. Our previous study successfully isolated the world's first E. anophelis phage, TCUEAP1, which showed beneficial protection to E. anophelis-infected mice. More new bacteriophages are needed in order to provide sufficient choices to combat E. anophelis infections. METHODS In the current study, two new phages infecting E. anophelis were isolated from wastewater and were designated as TCUEAP2 and TCUEAP3. Further experiments, namely, transmission electron microscopy (TEM), infection assay, host-range analysis, and sequencing were performed to determine their biological and genomic characteristics. RESULTS TEM analysis revealed that both TCUEAP2 and TCUEAP3 possess an icosahedral head with a non-contractile tail, and belong to the Siphoviridae family. Further experiments revealed that TCUEAP3 has a longer latent period and higher burst size compared to TCUEAP2. Host range analysis showed that both TCUEAP2 and TCUEAP3 have a narrow host range, infecting only their respective hosts. The genomic size of phage TCUEAP2 was 42,403 bps containing 61 predicted open reading frames (ORFs), whereas the genome size of TCUEAP3 was 37,073 bps containing 40 predicted ORFs. CONCLUSION Due to the distinct biological characteristics of TCUEAP2 and TCUEAP3, they may be satisfactory for clinical uses such as preparation of phage cocktails or decontamination in clinical settings.

Abstract
Schistosomiasis is a tropical parasitic disease, in which the major clinical manifestation includes hepatosplenomegaly, portal hypertension, and organs fibrosis. Clinically, treatment of schistosomiasis involves the use of praziquantel (PZQ) and supportive care, which does not improve the patient's outcome as liver injuries persist. Here we show the beneficial effects of using PZQ in combination with Schisandrin B (Sch B). Concomitant treatment with PZQ and Sch B resulted in a significant improvement of hepatosplenomegaly and fibrosis, compared with single-agent treatment. We also demonstrated that PZQ-Sch B treatment ameliorates injuries in the lungs and intestine better than the sole use of PZQ or Sch B. In addition, PZQ-Sch B treatment improves the survival of S. mansoni-infected mice, and the treatment combination yields better therapeutic outcomes, as indicated by a partial improvement in neurological function. These results were accompanied by a reduction in neurological injuries. Collectively, we suggest that PZQ-Sch B concomitant therapy may be useful to alleviate schistosomiasis-associated liver injuries and prevent systemic complications.

Abstract
After many years of the excessive use of praziquantel against Schistosoma mansoni (S. mansoni), it has already led to the development of drug resistance. While schistosomiasis is still affecting millions of people every year, vaccination may be one realistic alternative way to control the disease. Currently, S. mansoni 14-kDa fatty acid-binding protein (Sm14) has shown promising results as a vaccine antigen. Yet, the use of an adjuvant may be necessary to further increase the effectiveness of the vaccine. Herein, we investigated the potential of using heat-killed Cutibacterium acnes (C. acnes) as an adjuvant for recombinant Sm14 (rSm14). Immunization of mice with C. acnes-adjuvanted rSm14 showed increased humoral immune responses, compared with mice immunized with rSm14 alone. Additionally, C. acnes-adjuvanted rSm14 vaccination provided higher protection to mice against S. mansoni infection and liver injuries. These results suggest that C. acnes increases the immunogenicity of rSm14, which leads to better protection against S. mansoni infection. Therefore, heat-killed C. acnes may be a promising adjuvant to use with rSm14.

Abstract
Schistosomiasis is second only to malaria as the most devastating parasitic disease in the world. It is caused by the helminths Schistosoma mansoni (S. mansoni), S. haematobium, or S. japonicum. Typically, patients with schistosomiasis suffer from symptoms of liver fibrosis and hepatosplenomegaly. Currently, patients were treated with praziquantel. Although praziquantel effectively kills the worm, it cannot prevent re-infection or resolve liver fibrosis. Also, current treatment options are not ample to completely cure liver fibrosis and splenic damages. Moreover, resistance of praziquantel has been reported in vivo and in vitro studies. Therefore, finding new effective treatment agents is urgently needed. Schisandrin B (Sch B) of Schisandra chinensis has been shown to protect against different liver injuries including fatty liver disease, hepatotoxicity, fibrosis, and hepatoma. We herein investigate the potential of using Sch B to treat S. mansoni-induced liver fibrosis. Results from the present study demonstrate that Sch B is beneficial in treating S. mansoni-induced liver fibrosis and splenic damages, through inhibition of inflammasome activation and apoptosis; and aside from that regulates host immune responses. Besides, Sch B treatment damages male adult worm in the mice, consequently helps to reduce egg production and lessen the parasite burden.

Abstract
Breast cancer (BC) is a frequently diagnosed cancer among women worldwide. Currently, BC can be divided into different subgroups according to the presence of the following hormone receptors: estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2. Each of these subgroups has different treatment strategies. However, the presence of new metastatic lesions and patient deterioration suggest resistance to a given treatment. Various lines of evidence had shown that cytokines are one of the important mediators of tumor growth, invasion, metastasis, and treatment resistance. Interleukin-10 (IL-10) is an immunoregulatory cytokine, and acts as a poor prognostic marker in many cancers. The anti-inflammatory IL-10 blocks certain effects of inflammatory cytokines. It also antagonizes the co-stimulatory molecules on the antigen-presenting cells. Here, we review the current knowledge on the function and molecular mechanism of IL-10, and recent findings on how IL-10 contributes to the progression of BC.

Abstract
Currently, there are no effective treatments for liver diseases. Treatment usually involves controlling complications and supportive care. As liver injuries also affect other organs such as the spleen, kidney, and brain due to their anatomical and physiological relationships, finding an effective treatment is urgently needed. This research aimed to evaluate the therapeutic effect of Schisandrin B (Sch B) in the liver and other organs in thioacetamide (TAA)-intoxicated mice. In this study, mice were exposed to a single intraperitoneal injection of 200 mg/kg TAA to induce hepatitis. Following Sch B (20 mg/kg/day, 28 consecutive days) treatment, biochemistry analysis and histopathological examination of different organs were performed, in addition to western blotting and flow cytometry to evaluate the involvement of inflammasomes and apoptotic proteins. Our results showed that administration of Sch B protected against TAA-induced damages, and it disparately affected inflammasome activation and apoptosis in different organs. Furthermore, Sch B treatment improved organ function, as indicated by the improvement of serum biochemical parameters. Collectively, our findings reveal a beneficial effect of Sch B on different organ damages in mice intoxicated with TAA.

Abstract
Angiostrongylus cantonensis is one of the most widespread parasites causing central nervous system (CNS) diseases in mammals. Since the mitochondrion is an essential cell organelle responsible for both physiological and pathological processes, its dysfunction might lead to inflammation and multiple disorders. In this study we aimed to investigate the changes in mitochondrial dynamics that occur in the mouse brain upon infection with A. cantonensis, using molecular biology techniques such as polymerase chain reaction (PCR), western blot analysis, transmission electron microscopy (TEM), and different staining methods. Here, we show that mouse brain infected with A. cantonensis exhibits altered mitochondrial dynamics, including fission, fusion, and biogenesis. Additionally, we demonstrate that caspases and B-cell lymphoma 2 (BCL-2) were significantly upregulated in A. cantonensis-infected brain. These results are indicative of the occurrence of apoptosis during A. cantonensis infection, which was further confirmed by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining. These findings suggest the change in mitochondrial dynamics in A. cantonensis-infected brain, providing another point of view on the pathogenesis of meningoencephalitis caused by A. cantonensis infection.

Abstract
BACKGROUND Giardia duodenalis is a zoonotic protozoan parasite causing diarrhea through waterborne or fecal-oral infection. The cysts can live in the drinking water and cause pandemic diseases. In Taiwan, very little information is available regarding the epidemiology of G. duodenalis in domestic animals. METHODS Fecal samples were collected from cattle (n = 156) and pigs (n = 141) in Hualien country, eastern Taiwan. Detection and genotyping were done by microscopy examination of fecal samples and amplification of the β-giardin gene using nested PCR. RESULTS The prevalence of G. duodenalis infection was 19.87% for cattle (31/156) and 4.26% for pigs (6/141). Using nested PCR, 30 infected samples found in cattle belonged to Assemblage E, and one sample belonged to Assemblage D. For pigs, four samples belonged to Assemblage E, one belonged to Assemblage D, and another one belonged to Assemblage A. In addition, these results showed that G. duodenalis Assemblage A was detected in pigs and may cause zoonotic transmission. CONCLUSION This is the first epidemiological investigation of G. duodenalis infection in animals in Hualien, Taiwan. These results could provide epidemiological information for disease control and public health protection.
