Consumer Price Index (CPI) is an important indicator used to determine inflation. The main objective of this research was to compare the forecasting ability of two time-series models using Zambia Monthly Consumer Price Index. We used monthly CPI data which were collected from January 2003 to December 2017. The models that were compared are the Autoregressive Integrated Moving average (ARIMA) model and Multicointegration (ECM) model. Results show that the ECM was the best fit model of CPI in Zambia since it showed smallest errors measures. Lastly, a forecast was done using the ECM and results show an average growth rate for food CPI at 6.63% and an average growth rate for nonfood CPI at 7.41%. Forecasting CPI is an important factor for any economy because it is essential in economic planning for the future. Hence, identifying a more accurate forecasting model is a major contribution to the development of Zambia.

Bacterial meningitis (BM) is a life-threatening condition which affects the central nervous system (CNS). Its incidence rate is estimated between 0.22 - 2.66 and 0.81 - 6.1 cases/1000 lives worldwide and in Africa respectively. The objective of this study was to determine the frequency of bacterial organisms isolated from CSF of children less than five years old in Windhoek. A retrospective analysis was performed on 784 results of CSF submitted to the Namibia Institute of Pathology (NIP) from January 2010 to August 2014. The results showed that out of the suspected meningitis cases, 18 (28.6%) were due to Streptococcus pneumoniae, making it the frequently isolated organism, followed by Staphylococcus aureus 7 (11.1%), Escherichia coli 5 (7.9%) and Haemophilus influenzae 4 (6.3%). Streptococcus pneumoniae showed high resistance to penicillin 17 (70.5%) & cotrimoxazole 16 (93.7%) and 100% susceptibility to ciprofloxacin (5), vancomycin (13) & ceftri-axone (8). Haemophilus influenzae showed moderate resistance to cotrimoxazole 3 (66%) & tet-racycline 2 (50%). It showed 100% sensitivity to chloramphenicol (4), cefuroxime (2) & ceftriaxone (3). Neisseria meningitidis showed high resistance to cotrimoxazole by 100% (n = 2) and high sensitivity to chloramphenicol (n = 2), ceftriaxone & penicillin by 100% (n = 2). Streptococcus agalactiae was resistant to tetracycline and sensitive to penicillin & erythromycin by 100% (n = 1). Streptococcus pneumoniae was isolated the most in this current study and it had high resistance to penicillin & cotrimoxazole. There was a significant difference between results CSF culture and PCR, Gram stain, CSF cell count, protein & glucose, as all comparisons yielded in P values less than 0.05, indicating a significant statistical association.

Genital herpes, usually caused by Herpes Simplex Virus type-2 (HSV-2), is the commonest sexually transmitted disease especially amongst rural women in Southern Africa including Zimbabwe. This predisposes them to HIV/AIDS infection, cancer and opportunistic infections (OIs). Current antiviral treatments are often cytotoxic and/or ineffective. This motivates active research to find alternative safer drugs or lead drugs from traditional medicinal sources. Twenty six (26) methanol extracts from commonly used and often endangered plant species (14) used by communities and traditional medical practitioners for treating illnesses and sexually transmitted diseases from 5-selected districts of Zimbabwe were investigated for toxicity by Brine shrimp lethality test (BSLT) and by 50% Cytopathic effect on VERO cultured cells. The extracts were also tested for antiviral activity against Herpes Simplex Virus-2 (HSV-2) by the End Point Titration Technique (EPTT) and Neutralisation Test (NT) on VERO cells. Results from the BSLTs ranged 66.66 - 4304 μg/ml;50% Cytopathic effect from 19.53 - 312 μg/ml whilst the NT ID50 values ranged from 10.41 - 125 μg/ml. The antiviral EPTT reduction factor (RF) was 1 - 104 with 13 extracts showing RF ≥ 103. All the plant extracts had moderate to high toxicity (LC50, 789 - 66 μg/ml) in the BSLT. Six extracts had LC50 values greater than 1000 μg/ml. All 26 extracts were cytotoxic with CC50 values 50 in vitro therapeutic indexes ≥ 3.7. Cassia abbreviata, Dichrostachys cinerea and Hypoxis hemerocallidea had therapeutic indexes (TI) 7.5 - 15.0. The more active plant extracts were from roots and root tubers. The results confirm the rationale for the use of traditional medicinal plants by traditional medical practitioners for treating various diseases and could bring awareness for their better use and improve conservation.

Deletion or mutation of dentin matrix protein 1 （DMP1） leads to hypophosphatemic rickets and defects within the dentin. However, it is largely unknown if this pathological change is a direct role of DMP1 or an indirect role of phosphate （Pi） or both. It has also been previously shown that Klotho-deficient mice, which displayed a high Pi level due to a failure of Pi excretion, causes mild defects in the dentinal structure. This study was to address the distinct roles of DMP1 and Pi homeostasis in cell differentiation, apoptosis and mineralization of dentin and enamel. Our working hypothesis was that a stable Pi homeostasis is critical for postnatal tooth formation, and that DMP1 has an antiapoptotic role in both amelogenesis and dentinogenesis. To test this hypothesis, Dmpl-null （Dmpl-/-）, Klotho-deficient （kl/kl）, Dmpl/Klotho-double-deficient （Dmpl-/-/kl/kl） and wild-type （WT） mice were killed at the age of 6 weeks. Combinations of X-ray, microcomputed tomography （I^CT）, scanning electron microscopy （SEM）, histology, apoptosis and immunohistochemical methods were used for characterization of dentin, enamel and pulp structures in these mutant mice. Our results showed that Dmpl-/- （a low Pi level） or kl/kl（a high Pi level） mice displayed mild dentin defects such as thin dentin and a reduction of dentin tubules. Neither deficient mouse line exhibited any apparent changes in enamel or pulp structure. However, the double-deficient mice （a high Pi level） displayed severe defects in dentin and enamel structures, including loss of dentinal tubules and enamel prisms, as well as unexpected ectopic ossification within the pulp root canal. TUNEL assay showed a sharp increase in apoptotic cells in ameloblasts and odontoblasts. Based on the above findings, we conclude that DMP1 has a protective role for odontoblasts and ameloblasts in a pro-apoptotic environment （a high Pi level）.

To review the role of multidisciplinary management in treating sporadic duodenal adenomas (SDA). METHODSSDA managed at North Shore Hospital between 2009-2014 were entered into a prospective database. Pathology, endoscopic and surgical management as well as follow up were reviewed. RESULTSTwenty-eight patients (14 male: Median age 68 years) presented with SDA [18 were classified as non ampullary location (NA), 10 as ampullary location (A)]. All SDA were diagnosed on upper gastrointestinal endoscopy and were imaged with a contrast enhanced CT scan of the chest, abdomen and pelvis. Of the NA adenomas 14 were located in the second part, 2 in the first part and 2 in the third part of the duodenum. Two patients declined treatment, 3 patients underwent surgical resection (2 transduodenal resections and 1 pancreaticoduodenectomy), and 23 patients were treated with endoscopic mucosal resection (EMR). The only complication with endoscopic resection was mild pancreatitis post procedure. Patients were followed with gastroduodenoscopy for a median of 22 mo (range: 2-69 mo). There were 8 recurrences treated with EMR with one patient proceeding to pancreaticodeuodenectomy because of high grade dysplasia in the resected specimen and 2 NA recurrences were managed with surgical resection (distal gastrectomy for a lesion in the first part of the duodenum and a transduodenal resection of a lesion in the third part of the duodenum). CONCLUSIONSDA can be treated endoscopically with minimal morbidity and piecemeal resection results in eradication in nearly three quarters of patients. Recurrent SDA can be treated with endoscopic reresection with surgical resection indicated when the lesions are large (> 4 cm in diameter) or demonstrate severe dysplasia or invasive cancer.

在地球上广泛分布着像阿巴拉契亚盆岭省那样的褶皱一冲断层带,其形成年代为早元古代.本文列举了许多具有启发性的与第一部分所描述的"典型"实例所不同的变体.波状模式具有普遍性,在褶皱轴迹凸出段和凹进段,其走向弯曲可超过90°.褶皱轴迹凸出段的强烈弯曲似乎与克拉通构造凹人处的断层裂谷或拗拉槽有关.凹进段的强烈弯曲似乎与尖锐的克拉通岬角有关.与这些带有关的地层层序完全不同.绝大部分的上部地层层序包括源于造山带更内部的厚层状三角洲杂岩或其他碎屑楔,其下部变化较大,碎屑岩通常来源于克拉通边部.一些地层层序明显为大的厚层状浅海相碳酸盐岩,另一些主要为碎屑岩、火山碎屑岩或者包括一个薄层的非补偿性层序;而其他则为过渡性的.虽然沿着一些古老造山带绝大部分或所有边缘,缺失褶皱-冲断层带,但在挪威南部奥斯陆地堑中所保存下来的褶皱-冲断层带碎块表明其缺失仅仅是由于侵蚀较深,而使整个褶皱-冲断层带被剥蚀,暴露出其下部的原状基底.
